mgr/dashboard: cephfs subvolume list snapshots

Added a tab for displaying the subvolume snapshots
- this tab will show an info alert when there are no subvolumes present
- if the subvolume is present, then it'll be auto-selected by default

Implemented a filter to search the groups and subvolumes by its name.
Also added a scrollbar when there are too many items in the nav list

Modified the REST APIs to fetch only the names of the resources and
fetch the info when an API call is requesting for it.

Added unit tests

mds: encode `bal_rank_mask` using a higher (next) version

This is required for a reef client to work with a higher revision
MDS, since essentially, this happens:

reef(client):

if (version >=17) {
    decode(bal_rank_mask, p);
}

and higher-revision MDS (say, upcoming squid):

version = 17
encode(version, bl);
...
...
encode(max_xattr_size, bl);
encode(bal_rank_mask, bl);

The client incorrectly decodes max_xattr_size (type: uint64_t) into
bal_rank_mask (type: string).

This situation ended up due to a couple of reasons:

* the kclient patchset hanlding `max_xattr_size` was merged early on
  and another MDS side change that bumped the MDSMap encoding version
  to 17 got merged in the midst (PR #43284). Details in comment:

        https://github.com/ceph/ceph/pull/46357#issuecomment-1293556227

* The reef backport for PR #46357 got delayed (and, reef branched out).

Which means reef(18.2.0) user-space clients are broken with higher version
MDSs.

test/librbd: add DiffIterateTest.DiffIterateDeterministic{,PP}

scribble()-based DiffIterate tests are too weak: at least two
regressions that should been caught by DiffIterate.DiffIterate or
DiffIterate.DiffIterateStress were missed [1][2].  Aside from the
randomness which can be both a good and a bad thing, asserts there
ensure only that the returned diff covers all changes that were made.
If the returned diff is too excessive or otherwise bogus, this isn't
detected [3].

Add a deterministic test to systematically cover the most common cases
that don't involve discards.  A similar test for discards will be added
with the fix for [4].

librbd: fix read_whole_object handling in ObjectListSnapsRequest

Originally, in commit 2be4840afd4f ("librados/snap_set_diff: don't
assert on empty snapset"), exists was set to true.  This didn't make
ObjectListSnapsRequest, causing the following deep-copy tests to fail
when run against calc_snap_set_diff() rigged to return "whole object"
as described in [1]:

    TestDeepCopy.Snaps
    TestDeepCopy.SnapDiscard
    TestDeepCopy.CloneHideParent
    TestDeepCopy.Snaps_LargerDstObjSize
    TestDeepCopy.Snaps_SmallerDstObjSize

11923e234efc ("librbd: generic object list snapshot request").

librbd: fix LIST_SNAPS_FLAG_WHOLE_OBJECT behavior

Bundling read_whole_object and LIST_SNAPS_FLAG_WHOLE_OBJECT cases
together is wrong:

- In read_whole_object case, calc_snap_set_diff() sets just
  read_whole_object.  Everything else is zeroed out and may require
  resetting to fit with the rest of ObjectListSnapsRequest logic.

- In LIST_SNAPS_FLAG_WHOLE_OBJECT case, only the diff should be
  expanded.  Everything else is set by calc_snap_set_diff() and should
  be used as is.  This goes for end_size in particular -- if it's reset
  to object size, bogus zero extents may be returned as the object
  would appear to have grown.

This is a regression introduced in commit 4429ed4f3f4c ("librbd: switch
diff iterate API to use new snaps list dispatch methods") by way of
commit 66dd53d9c4d9 ("librbd: optionally return full object extent for

test/librbd: make ListSnapsWholeObject actually test stuff

Despite being added in commit 66dd53d9c4d9 ("librbd: optionally return
full object extent for any snapshot deltas") ostensibly to test the new
LIST_SNAPS_FLAG_WHOLE_OBJECT code, it surely doesn't do that because
the flag isn't even passed to MockObjectListSnapsRequest::create().

I can only guess, but it looks like snap ID 3 was intended to be
a starting point.  Otherwise, with 0 and CEPH_NOSNAP passed as snap
IDs, the overlap that is set up for the clone wouldn't affect the
computation in any way.

Use snap ID 3 as a starting point and run both with and without
LIST_SNAPS_FLAG_WHOLE_OBJECT on the same snapset to pinpoint the
difference.

Since commit 73f50a13109f ("rbd-mirror: use generalized deep copy for

end_size otherwise.

test/librbd: avoid config-related crashes in DiscardWithPruneWriteOverlap

For reasons that I think no longer apply today, set_val() and
set_val_or_die() refuse to set "type: str" config options that aren't
marked as "can be changed at runtime" -- set_val() returns an error and
set_val_or_die() terminates the process.  What is and isn't marked as
"can be changed at runtime" seems to be pretty much random both within
and outside of RBD, so let's just refactor how config is set here.

While at it, I realized that reproducer config is underspecified:

- for rbd_cache_policy and rbd_cache_writethrough_until_flush settings
  to matter, rbd_cache must be set to true and rbd_cache_max_dirty must
  be set to a positive number

- order should be set explicitly, because rbd_default_order can be as
  low as 12 (for 4096-byte objects), interfering with the logic of the
  test
