mgr/volumes: Disable quota for mgr libcephfs connection
This is done to give 'mgr' libcephfs connection right to bypass
quota. The mgr/volumes plugin maintains configuration files
with in the directory where the user has enforced quota. So
when the quota is met, certain mgr/volumes apis don't work as
intended. e.g., When subvolumegroup quota is met, the group's
subvolume removal with '--retain-snapshots' fails.

1. Set custom metadata for subvolume snapshot.
2. Set custom metadata for subvolume snapshot(Idempotency).
3. Get custom metadata for specified key.
4. Get custom metadata if specified key not exist (Expecting error ENOENT).
5. Get custom metadata if no any key-value is added means section not exist (Expecting error ENOENT).
6. Update value for existing key in custom metadata.
7. List custom metadata of subvolume snapshot.
8. List custom metadata of subvolume snapshot if no any key-value is added (Expect empty json/dictionary)
9. Remove custom metadata for specified key.
10. Remove custom metadata if specified key not exist (Expecting error ENOENT).
11. Remove custom metadata if no any key-value is added means section not exist (Expecting error ENOENT).
12. Remove custom metadata with --force option.
13. Remove custom metadata with --force option if specified key not exist (Expecting command to succeed because of '--force' option)
14. Remove subvolume snapshot and verify whether metadata for snapshot is removed or not
docs: set, get, list and remove custom metadata for snapshot
Set custom metadata on the snapshot as a key-value pair using
$ ceph fs subvolume snapshot metadata set <vol_name> <subvol_name> <snap_name> <key_name> <value> [--group_name <subvol_group_name>]
note: If the key_name already exists then the old value will get replaced by the new value.
note: The key_name and value should be a string of ASCII characters (as specified in python's string.printable). The key_name is case-insensitive and always stored in lower case.
note: Custom metadata on a snapshots is not preserved when snapshotting the subvolume, and hence, is also not preserved when cloning the subvolume snapshot.
Get custom metadata set on the snapshot using the metadata key::
$ ceph fs subvolume snapshot metadata get <vol_name> <subvol_name> <snap_name> <key_name> [--group_name <subvol_group_name>]
List custom metadata (key-value pairs) set on the snapshot using::
$ ceph fs subvolume snapshot metadata ls <vol_name> <subvol_name> <snap_name> [--group_name <subvol_group_name>]
Remove custom metadata set on the snapshot using the metadata key::
$ ceph fs subvolume snapshot metadata rm <vol_name> <subvol_name> <snap_name> <key_name> [--group_name <subvol_group_name>] [--force]
Using the '--force' flag allows the command to succeed that would otherwise fail if the metadata key did not exist.
mgr/volumes: set, get, list and remove custom metadata for snapshot
If CephFS in ODF configured in external mode, user like to use
subvolume snapshot metadata to store some Openshift specific
information, as the PVC/PV/namespace the subvolumes/snapshot
are coming from. For RBD volumes, it's possible to add metadata
information to the images using the 'rbd image-meta' command.
However, this feature is not available for CephFS volumes.
We'd like to request this capability.

mon/OSDMonitor: Ensure kvmon() is writeable before handling "osd new" cmd
Before proceeding to handle "osd new" mon command as part of
OSDMonitor::prepare_command_impl(), a check is made to verify if the
authmon is writeable. Later on, prepare_command_osd_new() invokes
KVMonitor::do_osd_new() to create pending dmcrypt keys and calls
propose_pending(). The propose could fail (with an assertion failure)
if there was a prior mon command that resulted in the kvmon invoking
propose_pending().
In order to avoid such a situation, introduce a check to verify that
kvmon is also writeable in OSDMonitor::prepare_command_impl(). If it
is not writeable, the op is pushed into the wait_for_active context
queue to be retried later.

Although the chunking in off-line `dups` trimming (via COT) seems
fine, the `ceph-objectstore-tool` is a client of `trim()` of
`PGLog::IndexedLog` which means than a partial revert is not
possible without extensive changes. Moreover, trimming pg log
is not enough without modifying pg_info_t accordingly which
the reverted patch lacks.
