doc/rados/operations: add kernel client procedure to read balancer documentation
As of now, the kernel client does not support `pg-upmap-primary`. I have
added some troubleshooting steps to help users who are unable to
mount images and filesystems with the kernel client while using `pg-upmap-primary`.
Once the feature is supported by the kernel client, users will be able
to perform mounts along with `pg-upmap-primary`.

rgw/logging: fixes data loss during rollover
Multiple threads attempting to roll over the same log object can result
in the creation of numerous orphan tail objects, each with a single record.
This occurs when a NULL RGWObjVersionTracker is used during the creation of
a new logging object. These records are inaccessible, leading to data loss,
which is particularly critical in Journal mode.
Furthermore, valid log tail objects may be added to the Garbage Collection (GC)
list, exacerbating data loss.

common: Added values to json::OSDPoolGetReply
OSDPoolGetReply actually returns a lot more values than what is currently supplied. These have been added in as optionals (as they can not be give as well) so its possible to query them to find out if they exist and use them if they do.

Modify collect_omap_stats() to guarantee that only
one 'large omap entry' warning message is logged
per chunk, thus maintaining the existing behaviour.
Unlike the existing behaviour - all 'large omap'
entries are counted.

build-with-container: ensure npm dir is set up before configure
When the npm cache path option is passed the npm cache dir is passed
to all container `run` commands, ensure the dir has been created
before the first container command (configure) is used.

according to `dpkg-buildflags`, ubuntu 24 raised this value to
`-D_FORTIFY_SOURCE=3` which causes `error: "_FORTIFY_SOURCE" redefined`
compilation failures because Ceph itself adds `-D_FORTIFY_SOURCE=2`
`_FORTIFY_SOURCE` is a hardening option. both our rpm and debian builds
already specify that via environment variables, so Ceph's cmake should
leave it alone
Update the "Disconnected+Remounted FS" section in
doc/cephfs/troubleshooting.rst, as suggested by Venky Shankar in https://github.com/ceph/ceph/pull/65129/files#r2312903062
osd: stop scrub_purged_snaps() from ignoring osd_beacon_report_interval
OSD beacons could be burdersome to the enitre cluster, as they lead
to generation of new `OSDMap` epochs. Therefore their frequency is
restricted through `osd_beacon_report_interval` to 5 mins by default.
Unfortunately, the `OSD::send_purged_snaps()` is unaware about this
policy with the net result being storm of OSDMaps. This patch unifies
its behavior with `OSD::tick_without_osd_lock()`.
This is unsafe because bufferlist data is not guaranteed to be null-
terminated. The std::string constructor searches for a null terminator
and may read beyond the bufferlist's allocated memory, causing a
heap-buffer-overflow detected by AddressSanitizer:

Fix by using bufferlist::length() which tells if the given buffer is
empty instead of converting the buffer content to a string.
