In preparation for push support in sync jobs.
Extend and move `BackupStats` into `backup_stats` submodule and add
method to create them from `UploadStats`.
Further, introduce `UploadCounters` struct to hold the Arc clones of
the chunk upload statistics counters, simplifying the house keeping.
By bundling the counters into the struct, they can be passed as
single function parameter when factoring out the common stream future
in the subsequent implementation of the chunk upload for sync jobs
in push direction.

In preparation for implementing push support for sync jobs.
Factor out the upload stream for merged chunks, which can be reused
to upload the local chunks to a remote target datastore during a
snapshot sync operation in push direction.

Add a method `upload_index_chunk_info` to be used for uploading an
existing index and the corresponding chunk stream.
Instead of taking an input stream of raw bytes as the
`upload_stream`, this takes a stream of `MergedChunkInfo` object
provided by the local chunk reader of the sync jobs source.

Changes since version 5:
- refactor to adapt to UploadCounter changes
- fixes incorrect compressed stream counter

Combine the two if statements checking the datastores ACL path
components, which can be represented more concisely as one.
Further, extend the pre-existing comment to clarify that `datastore`
ACL paths are not limited to the datastore name, but might have
further sub-components specifying the namespace.

Extend the component limit for ACL paths of `remote` to include
possible namespace components.
This allows to limit the permissions for sync jobs in push direction
to a namespace subset on the remote datastore.

Add a `remote_acl_path` helper method for creating acl paths for
remote namespaces, to be used by the priv checks on remote datastore
namespaces for e.g. the sync job in push direction.
Factor out the common path extension into a dedicated method.

Also, rename the private field `unremoved_protected` to a better
fitting `protected_snapshots` to be in line with the method names.

Make the `BackupGroupDeleteStats` exposable via the API by implementing
the ApiTypes trait via the api macro invocation and add an additional
field to account for the number of deleted groups.
Further, add a method to add up the statistics.

Add a dedicated api type for the `version` api endpoint and helper
methods for supported feature comparison.
This will be used to detect api incompatibility of older hosts, not
supporting some features.
Use the new api type to refactor the version endpoint and set it as
return type.

changes since version 5:
- add `features` vector to store supported feature strings
- drop `min_version_check`, introduce `supported_feature` check

Adds the functionality required to push datastore contents from a
source to a remote target.
This includes syncing of the namespaces, backup groups and snapshots
based on the provided filters as well as removing vanished contents
from the target when requested.
While trying to mimic the pull direction of sync jobs, the
implementation is different as access to the remote must be performed
via the REST API, not needed for the pull job which can access the
local datastore via the filesystem directly.
Signed-off-by: Christian Ebner <c.ebner@proxmox.com>

changes since version 5:
- fetch backup groups split by owned and not owned, only allow to push
to owned groups, don't allow to prune not owned groups.
- store remote api version unconditionally
- check for supported feature instead of api version to include conditional
parameters for api calls
- directly use delete stats from api calls, since these are not followup
patches anymore

configure the direction of the job.
Adds an additional config type `sync-push` to the sync job config, to
clearly distinguish sync jobs configured in pull and in push
direction and defines and implements the required `SyncDirection` api
type.
This approach was chosen in order to limit possible misconfiguration,
as unintentionally switching the sync direction could potentially
delete still required snapshots.

Expose the sync job in push direction via a dedicated API endpoint,
analogous to the pull direction.

changes since version 5:
- Avoid double deserialization for backup namespaces
- Drop TryFrom<&SyncJobConfig> for PushParameters impl, as constructing
them requires an api call to fetch the remote api version now

Read access to sync jobs is not granted to users not having at least
PRIV_DATASTORE_AUDIT permissions on the datastore. However a user is
able to create or modify such jobs, without having the audit
permission.
Therefore, further restrict the modify check by also including the
audit permissions.

Move the sync job owner check to its own helper function, for it to
be reused for the owner check for sync jobs in push direction.
No functional change intended.

Exposes and switch the config type for sync job operations based
on the `sync-direction` parameter, exposed on required api endpoints.
If not set, the default config type is `sync` and the default sync
direction is `pull` for full backwards compatibility. Whenever
possible, deterimne the sync direction and config type from the sync
job config directly rather than requiring it as optional api
parameter.
Further, extend read and modify access checks by sync direction to
conditionally check for the required permissions in pull and push
direction.

changes since version 5:
- Squashed permission check patches into this one, as they make not much
sense without this
- Only expose optional sync-direction parameter for api endpoints which
require them, use the job config to determine sync-direction and/or
config-type otherwise.

`list_sync_jobs` exists as api method in `api2::admin::sync` and
`api2::config::sync`.
Rename the admin api endpoint method to `list_config_sync_jobs` in
order to reduce possible confusion when searching/reviewing.
No functional change intended.

The namespace has to be set in order to get the correct groups to be
used as group filter options with a local datastore as source,
required for sync jobs in push direction.

Switch to the local datastore, used as sync source for jobs in push
direction, to get the available group filter options.

In order to load data using the same model from different sources,
set the proxy on the store instead of the model.
This allows to use the view to display sync jobs in either pull or
push direction, by setting the `sync-direction` ont the view.

Add and expose the backup group delete statistics by adding the
return type to the corresponding REST API endpoints.
Further, add a `error-on-protected` flag to the api endpoints,
allowing to return without error when set to false. Default remains
enabled.

changes since version 5:
- rename optional api parameter from `ignore-protected` to `error-on-protected`

Expose the 'prune-delete-stats' as supported feature, in order for
the sync job in pull direction to pass the optional
`error-on-protected=false` flag to the api calls when pruning backup
snapshots, groups or namespaces.

Documents the caveats of sync jobs in push direction, explicitly
recommending setting up dedicted remotes for these sync jobs.

+Sync Direction Push
+^^^^^^^^^^^^^^^^^^^
+
+Sync jobs can be configured for pull or push direction. Sync jobs in push
+direction are not identical in behaviour because of the limited access to the
+target datastore via the remote servers API. Most notably, pushed content will
+always be owned by the user configured in the remote configuration, being
+independent from the local user as configured in the sync job. Latter is used
+exclusively for permission check on the pushing side.
+
+.. note:: It is strongly advised to create a dedicated remote configuration for
+ each individual sync job in push direction, using a dedicated user on the
+ remote. Otherwise, sync jobs pushing to the same target might remove each
+ others snapshots and/or groups, if the remove vanished flag is set or skip
+ snapshots if the backup time is not incremental.
+ This is because the backup groups on the target are owned by the user
+ given in the remote configuration.
+
+The following permissions are required for a sync job in push direction:
+
+#. ``Remote.Audit`` on ``/remote/{remote}`` and ``Remote.DatastoreBackup`` on
+ ``/remote/{remote}/{remote-store}/{remote-ns}`` path or subnamespace.
+#. At least ``Datastore.Read`` on the local source datastore namespace
+ (``/datastore/{store}/{ns}``)
+#. ``Remote.DatastorePrune`` on ``/remote/{remote}/{remote-store}/{remote-ns}``
+ path to remove vanished snapshots and groups. Make sure to use a dedicated
+ remote for each sync job in push direction as noted above.
+#. ``Remote.DatastoreModify`` on ``/remote/{remote}/{remote-store}/{remote-ns}``
+ path to remove vanished namespaces. A remote user with limited access should
+ be used on the remote backup server instance. Consider the implications as
+ noted below.
+
+.. note:: ``Remote.DatastoreModify will allow to remove whole namespaces on the
+ remote target datastore, independent of ownership. Make sure the user as
+ configured in remote.cfg has limited permissions on the remote side.
