This PR undoes the backporting of https://github.com/ceph/ceph/pull/46089

mgr/telemetry: handle daemons with complex ids
Treating daemons as `<daemon_type>.x` caused a crash
in the Telemetry module since the current method does not cover a case
where a daemon id is more complex, i.e. `<daemon_type>.x.y`.
When we parse the daemon type and daemon id, we should
split it into a maximum of two pieces rather than splitting
it by every `.` character. Specifying `1` in the Python
.split() function will limit the split to a maximum of two items.

test/librbd: various fixups for compare-and-write test cases
- missing EILSEQ asserts in IO and IOWithIOHint
- AioCompletion leak in CompareTooSmall and WriteTooSmall
- skip StripeUnitUnaligned and TooLarge on the PWL cache as it wasn't
limited by the 512-byte sector limit before and isn't limited by the
stripe unit limit now
cmp_bl can no longer be shorter than read_bl (i.e. image extent).
This is caught very early at the API level, see commit af96e6dae3f4
("librbd: make C++ cmp&write semantics equal to C API").
However, cmp_bl can still be longer than read_bl and in that case
it should be capped by the image extent length.

librbd: discard cache state if compare-and-write writes to disk
Otherwise this is obviously broken with rbd_cache_policy = writeback or
rbd_cache_policy = writethrough as the write is done on the OSD, beneath
ObjectCacher. This went unnoticed because the original (and so far the
only known) compare-and-write user, tcmu-runner rbd driver, disables the
cache altogether.

librbd: make C++ cmp&write semantics equal to C API
The compare and write C++ API (both sync and async) does not check
compare bufferlist length and executes compare ops of bufferlist length
size, even if (write) "len" is smaller than bufferlist length.
This patch changes this behavior by always issuing compares and
writes of "len" size to match the C API. The bufferlist length
can be greater than "len" for both compare and write but only
"len" bytes are compared and written. If the bufferlist length
is smaller than "len" the call will fail.

This patch removes the compare and write max sector size len

To allow larger size compare and write requests in the

The devices section in the OSD Details and Host Details shows more than
one daemon and device path in the column when you view the details of a
single osd details/host details. This is because more than one osd
is created on a device with same `deviceid`. I am not sure if this will
happen in the real environment but its mostly reproducible in
environments with QEMU emulated devices.

This commit makes several refinements to the English in

This PR updates the prompts in crush-map-edits.rst

There remains no good known way to render parts of
a file if the first line of that file begins with a
hash (#). Sphinx italicizes such a first line, which
is not what I want. Two examples of this are present

"CRUSH Map Bucket Types". I set this down here for
my own records, in case it is helpful in finding a
way to make these sections render as I would prefer.
