[pbs-devel] [PATCH proxmox-backup v3 00/24] add removable datastores

[Hannes Laimer <h.laimer@proxmox.com>]

These patches add support for removable datastores. All removable
datastores have a backing-device(a UUID) associated with them. Removable
datastores work like normal ones, just that they can be unplugged. It is
possible to create a removable datastore, sync backups onto it, unplug
it and use it on a different PBS.

The datastore path is also the mountpoint for the removable datastore.
By default when creating one through the web UI it will be
`/mnt/removable-datastores/<UUID>`, using the CLI it is possible to
specify something else. Since a removable datastore is associated with
the UUID of a partition, it is technically possible to have two
removable datastores on the same device, but I don't think there is a
use-case that couldn't also be done using namespaces.

When a removable datastore is deleted and 'destroy-data' is set, the
device has to be plugged in. If 'destroy-data' is not set the datastore
can be deleted even if the device is not present. Removable datastores
are automatically mounted when plugged in. At the API service start all
removable datastores are marked as 'unplugged', unless they are already
mounted.

Patches 21/24 and 23/24 are not strictly needed, but they made sense in
this context, so I kept them in this series. 

 
v3:
 * remove lazy unmounting (since 9cba51ac782d04085c0af55128f32178e5132358 is applied)
 * fix CLI (un)mount command, thanks @Gabriel
 * add removable datastore CLI autocomplete helper
 * rebase onto master
 * move ui patches to the end

thanks @Lukas and @Thomas for the feedback
v2:
 * fix datastore 'add' button in the UI
 * some format!("{}", a) -> format!("{a}")
 * replace `const` with `let` in js code
 * change icon `fa-usb` -> `fa-plug`
 * add some docs
 * add JDoc for parseMaintenanceMode
 * proxmox-schema dep bump
