mgr/rbd_support: recover from rados client blocklisting
In certain scenarios the OSDs were slow to process RBD requests.
This lead to the rbd_support module's RBD client not being able to
gracefully handover a RBD exclusive lock to another RBD client.
After the condition persisted for some time, the other RBD client
forcefully acquired the lock by blocklisting the rbd_support module's
RBD client, and consequently blocklisted the module's RADOS client. The
rbd_support module stopped working. To recover the module, the entire
mgr service had to be restarted which reloaded other mgr modules.
Instead of recovering the rbd_support module from client blocklisting
by being disruptive to other mgr modules, recover the module
automatically without restarting the mgr serivce. On client getting
blocklisted, shutdown the module's handlers and blocklisted client,
create a new rados client for the module, and start the new handlers.

librbd: localize snap_remove op for mirror snapshots
A client may attempt a lock request not quickly enough to
obtain exclusive lock for operations when another competing
client responds quicker. This can happen when a peer site has
different performance characteristics or latency. Instead of
relying on this unpredictable behavior, localize operation to
primary cluster.

qa/: Override mClock profile to 'high_recovery_ops' for qa tests
The qa tests are not client I/O centric and mostly focus on triggering
recovery/backfills and monitor them for completion within a finite amount
of time. The same holds true for scrub operations.
Therefore, an mClock profile that optimizes background operations is a
better fit for qa related tests. The osd_mclock_profile is therefore
globally overriden to 'high_recovery_ops' profile for the Rados suite as
it fits the requirement.
Also, many standalone tests expect recovery and scrub operations to
complete within a finite time. To ensure this, the osd_mclock_profile
options is set to 'high_recovery_ops' as part of the run_osd() function
in ceph-helpers.sh.
A subset of standalone tests explicitly used 'high_recovery_ops' profile.
Since the profile is now set as part of run_osd(), the earlier overrides
are redundant and therefore removed from the tests.
doc/: Modify mClock configuration documentation to reflect profile changes
Modify the relevant documentation to reflect:
- change in the default mClock profile to 'balanced'
- new allocations for ops across mClock profiles
- change in the osd_max_backfills limit
- miscellaneous changes related to warnings.
common/options/osd.yaml.in: Change mclock max sequential bandwidth for SSDs
The osd_mclock_max_sequential_bandwidth_ssd is changed to 1200 MiB/s as
a reasonable middle ground considering the broad range of SSD capabilities.
This allows the mClock's cost model to extract the SSDs capability
depending on the cost of the IO being performed.
osd/: Retain the default osd_max_backfills limit to 1 for mClock
The earlier limit of 3 was still aggressive enough to have an impact on
the client and other competing operations. Retain the current default
for mClock. This can be modified if necessary after setting the
osd_mclock_override_recovery_settings option.

osd/scheduler: simplify qos specific params in OpSchedulerItem
is_qos_item() was only used in operator<< for OpSchedulerItem. However,
it's actually useful to see priority for mclock items since it affects
whether it goes into the immediate queues and, for some types, the
class. Unconditionally display both class_id and priority.
osd: Retain overridden mClock recovery settings across osd restarts
Fix an issue where an overridden mClock recovery setting (set prior to
an osd restart) could be lost after an osd restart.
For e.g., consider that prior to an osd restart, the option
'osd_max_backfill' was successfully set to a value different from the
mClock default. If the osd was restarted for some reason, the
boot-up sequence was incorrectly resetting the backfill value to the
mclock default within the async local/remote reservers. This fix
ensures that no change is made if the current overriden value is
different from the mClock default.
Modify an existing standalone test to verify that the local and remote
async reservers are updated to the desired number of backfills under
normal conditions and also across osd restarts.
