ENOTDIR is raised instead of EINVAL which is better
aligned with the nature of the failure

- test_nfs_export_creation_at_symlink:
ENOTDIR is raised instead of ENOENT since the code
can now check if the path is symlink but won't follow
it.

qa: fix test_nfs_export_with_invalid_path

It actually didn't test the invalid path but still ended with
ENOENT(which is expected in case path is invalid) as the test
didn't create a fs, and it failed saying "FS nfs-cephfs not found"
which too raises ENOENT and thus it always passed.

mgr/nfs/utils: changes to helper func to check cephfs path

- Renamed to cephfs_path_is_dir

- Removed exception handling to prevent redundant log statements like:
   "No such file or directory error in stat: b'/mnt/testdir_symlink': No such file or directory [Errno 2]"

  Exceptions handled inside caller eliminates this redundancy

- Set modifier flag AT_SYMLINK_NOFOLLOW

- Removed string "{path} is not a dir" when raising NotADirectoryError
  Rationale: will be handled in export.py

- change mock to cephfs_path_is_dir

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.

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

for mClock. This can be modified if necessary after setting the
