This PR rewrites a section in the Troubleshooting
chapter of the Cephadm Guide. The material that this
section discusses has been covered already in the
Cephadm Guide in the Cephadm Operations chapter.
There's no reason to repeat this information twice,
unless adding technical debt to the documentation
is our goal (which of course it is not, and the
opposite of adding technical debt to the documentation
has been the aim that has guided my work these past
six months).

admin, doc: introduce sphinxcontrib.seqdiag
for rendering sequence-diagram. unlike ditaa, seqdiag allows us to
create sequence-diagram without worrying about the layout. and the
syntax is quite like that of dot.
set(dpdk_LIBRARIES) does not reset this variable, it leaves it
unchanged.
if pkg-config manages to find DPDK libraries, dpdk_LIBRARIES would be
set with a string like "rte_node;rte_graph;..." by
pkg_check_modules(dpdk QUIET libdpdk).
but we would want to set this variable to the import paths of the
required libraries. so reset it before appending them to this variable.
this change helps to address the build failure when building Ceph with
DPDK installed into system along with its .pc file.

mon,mds: use per-MDS compat to inform replacement
This diff makes the following changes:
- FSMap::compat is now just a "default compat" of currently unknown
utility. It is used when constructing a new file system but does
not really have any effect or current use.
- The `mds compat *` CLI commands are deprecated. They manipulate
the default compat which has no useful effect.
- Each MDS sends its compat to the mons in its beacon. This is from
MDSMap::get_compat_set_all() at MDS boot. This CompatSet does not
change for the duration of the MDS lifetime.
- Mons record each MDS compat in the FSMap to inform standby failover.
An MDS is only promoted if it is compatible with the file system
compat.
- Mons upgrade (merge) the file system compat when (a) the number of
*in* MDS is 1 (effected by max_mds=1) and (b) the mons are promoting a
standby with a new compat. A file system is never upgraded when there
is more than 1 rank to prevent two MDS with incompatible compat.
- A suite of `fs compat` commands exist to manipulate the file system
compat. These exist mostly for testing.
The consequence of these changes is that the upgrade procedure for MDS
can be updated to no longer require turning off all MDS but rank 0
before performing any upgrades. A CompatSet change would cause all MDS
receiving the new MDSMap to suicide due to incompatibility (if so).
Instead, the monitors will no longer assign an incompatible MDS to a
file system and enforce an upgrade procedure if incompatibilities exist.

mon: do not update inline incompat except via mds
The MDS_FEATURE_INCOMPAT_INLINE feature indicates that an MDS knows how
to read/write inline data and that the file system may have it. The
separate setting for inline_data protects this file system feature.

This was partially done in b94c8de but only for haproxy in the cephadm
mgr module not in the cephadm binary.
This adds the same change for keepalived container image.
Now both haproxy and keepalived container images are fully qualified
(registry + namespace + image).
With the implementation of DBStore, it was determined that the API used
for writing in Zipper was too tied to RADOS. Implement a clean writing
API named Writer.

qa/standalone/scrub: Force a subset of scrub tests to use "wpq" scheduler
The following tests in the test files mentioned below use the
"osd_scrub_sleep" option to introduce delays during scrubbing to help
determine scrubbing states, validate reservations during scrubbing etc..
This works when using the "wpq" scheduler.
But when the "mclock_scheduler" is enabled, the "osd_scrub_sleep" is
disabled and overridden to 0. This is done to delegate the scheduling of
the background scrubs to the "mclock_scheduler" based on the set QoS
parameters. Due to this, the checks to verify the scrub states,
reservations etc. fail since the window to check them is very short
due to scrubs completing very quickly. This affects a small subset of
scrub tests mentioned below,
Only for the above tests, until there's a reliable way to query scrub
states with "--osd-scrub-sleep" set to 0, the "osd_op_queue" config
option is set to "wpq".

osd: Add a new config option to forcibly run OSD benchmark on init
The new config option "osd_mclock_force_run_benchmark_on_init" is
introduced to allow a user to force run the OSD benchmark test on every
OSD boot-up even if the historical data about the OSD's iops capacity is
available on the MON config store. The 'force_run_benchmark' flag is set
to the value indicated by the new config option.
By default this new config option is set to false.
The utility of this option is to help refresh the OSD iops capacity
when the underlying device's performance characteristics have changed
significantly. In such cases, the OSD can be restarted with this option
enabled temporarily. Once the new iops capacity is updated to the MON
store, this option can be removed from the OSD's start-up config.
osd: Add mechanism to avoid running OSD benchmark on every OSD boot-up
Use "mon_cmd_set_config()" to store the OSD's max iops capacity to
the MON store during the first bring-up. Don't run the OSD benchmark
test on subsequent boot-ups if a previously persisted iops capacity is
available on the MON store and is different from the default iops
capacity.
Add the 'force_run_benchmark' flag to force a run of the benchmark
in case the default iops capacity cannot be determined.
common/config: Add methods to return the default value of a config option
Add wrapper method "get_val_default()" to the ConfigProxy class that takes
the config option key to search. This method in-turn calls another method
with the same name added to md_config_t class that does the actual work of
searching for the config option. If the option is valid, _get_val_default()
is used to get the default value. Otherwise, the wrapper method returns
std::nullopt.
