[PATCH proxmox{,-backup} v2 0/6] fix #7078: Add quirk for providers not supporting deleteObjects

[Christian Ebner <c.ebner@proxmox.com>]

These patches provide a workaround to users which would like to
use the S3 datastore backend with object store API's not implementing
the deleteObjects API method, such as e.g. Google Cloud Storage.

When the quirk is set via the S3 client options, delete objects calls
are performed as individual delete object calls instead.

Patches therefore restructure the s3-client code such that the delete
objects response can be generated and the deletion is performed by
looping over the delete list, performing single object deletions.

On the Proxmox Backup Server side the new, additional quirk is exposed
by reworking the advanced section in the s3 endpoint edit window
to use a fieldset of checkboxes instead of the dropdown selector,
with the intend to improve usability.

Changes since version 1 (thanks @Fabian for review):
- Improve error handling for delete object(s) api calls.
- Retrieved and log delete errors on PBS side.
