The teuthology branch to run against.
Default value is determined in the next order.
There is TEUTH_BRANCH environment variable set.
There is `qa/.teuthology_branch` present in
the suite repo and contains non-empty string.
There is `teuthology_branch` present in one of

The .teuthology_branch file in the qa/ dir currently points at "master".
Change it to point to "main".

osd/scrub: restart snap trimming after a failed scrub
A followup to PR#45640.
In PR#45640 snap trimming was restarted (if blocked) after all
successful scrubs, and after most scrub failures. Still, a few
failure scenarios did not handle snaptrim restart correctly.
The current PR cleans up and fixes the interaction between
scrub initiation/termination (for whatever cause) and snap
trimming.

qa/config: override `bluestore_zero_block_detection` default for rados suite tests
By default, `bluestore_zero_block_detection` is false since it interacts
negatively with some RBD and CephFS features. We still want this enabled
for rados teuthology tests though so we can use it for large-scale testing.
Adding this setting to the rados teuthology config file will override the global
config setting and enable `bluestore_zero_block_detection` only for tests in
the teuthology rados suite.

os/bluestore: turn bluestore zero block detection off by default
This commit adds a new global config option called `bluestore_zero_block_detection`.
This option is used at a dev level to skip zero bufferlist writes in large-scale
testing scenarios.
Store tests originally written for the BlueStore zero block detection feature
now account for the global config option; these tests will only run if
`bluestore_zero_block_detection` is set to "true".

crimson/os/seastore/segment_cleaner: add dedicated backref trimming process
Space reclamation needs to merge backrefs up to the point where the latest
release of extents within the scope of the reclamation process happened.
When the journal size is large, that merge may generate a transaction
record with size exceeds the max record size threshold. So we need have a
backref trimming process that merge most of the backrefs before the space
reclamation happens.
This commit also fixes issue: https://tracker.ceph.com/issues/55692, by
repeating the inflight backrefs trimming transaction when it's
invalidated by other trans on the ROOT block
qa: set, get, list and remove custom metadata for snapshot
Following test are added:
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

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.

client: stop retrying the request when exceeding 256 times
The type of 'retry_attempt' in 'MetaRequest' is 'int', while in
'ceph_mds_request_head' the type of 'num_retry' is '__u8'. So in
case the request retries exceeding 256 times, the MDS will receive
a incorrect retry seq.
In this case it's ususally a bug in MDS and continue retrying the
request makes no sense. For now let's limit it to 256. In future
this could be fixed in ceph code, so avoid using the hardcode here.

as per https://www.json.org/json-en.html, JSON encodes bool as
"true" or "false", without the quotes. before this change, the quotes
are always added when encoding boolean values.
but this change is not backward compatible.
encode_json()'s bool overload is used by rgw. it uses JSONObj
defined in common/ceph_json.h to decode JSON-encoded structs.
and it does not differentiate bool from str when decoding a boolean
value despite that it could have check the "quoted" member variable
of JSONObj for validating the type of value. so we should be fine.
but gcc-toolset-8-annobin provides this file. upgrading to
gcc-toolset-11 does not help. see https://centos.pkgs.org/8-stream/centos-appstream-x86_64/gcc-toolset-11-annobin-plugin-gcc-10.23-1.el8.x86_64.rpm.html
so, the intermediate solution would be to disable the plugin, if
we want to use gcc-toolset to build rpm packages.
in this change, _annotated_build is undefined to prevent the compiler
from adding extra information to the binary. in general this change
shuold be safe, without these information, it'd be hard to tell if
the binary is hardened or what ABI version it expects. see
