doc/radosgw: fix formatting
Repair the formatting of a string that had a string inside backticks
that itself was inside double asterisks. The presence of the asterisks
around the entire string caused the backticks to appear in the rendered
documentation.
fs suite relies on these debugfs entries to gather mount information
(client-id, addr/inst) which are required by some tests. In fs suite,
the disto kernel gets overridden by the testing kernel and therefore
even if Ubuntu 20.04 is chosen as the distro, the testing kernel is
installed. However, with smoke suite, the distro kernel is used and
the missing patches causes certain essential information gathering to
fail early on (client-id, etc..) causing the test to not even start
execution. PR #54515 fixes a bug in the client-id fetching path but
isn't complete due to the missing patches - details here:
https://tracker.ceph.com/issues/63488#note-8
But its essential to have the smoke tests running since those tests
have lately uncovered bugs in the MDS (w/ distro kernels). In order
to benefit from those tests, this change ignores failures when
gathering mount information (which aren't used by the fs relevant
smoke tests). The test (in fs suite) that rely on this piece of
information would fail when run with 20.04 distro kernel (but the
fs suite overrides it with the testing kernel).

qa: add centos_latest (9.stream) and ubuntu_20.04 yamls to supported-all-distro
A bug in Ceph MDS (MDS crash!) is seen with distos using a not-so-recent kernel
(5.4ish). This crash was first seen in quincy smoke run and the problematic
backport change was reverted. The smoke suite chooses a random distro for each
job, so to hit this bug, the appropriate distro needs to be (randomly) get chosen.
This change point the smoke suite to run against all supported distros.
This effects suites that point to supported-all-distro (powercycle) since it
bloats up the number of jobs. E.g., currently, without --subset, powercycle:osd
INFO:teuthology.suite.run:0/336 jobs were filtered out.
vs
(with this change)
Unable to schedule 560 jobs, too many jobs, when maximum 500 jobs allowed.
For smoke suite
INFO:teuthology.suite.run:Scheduled 24 jobs in total.
vs
(with this change)
INFO:teuthology.suite.run:Scheduled 120 jobs in total.
Eventually, with PR #46882, then testing kernel will no longer override the
distro kernel in fs suite, so we should get good coverage then.

mgr/dashboard: Consider null values as zero in grafana panels
After upgrading from RHCS4 to RHCS5..some of the grafana charts broke.
This is because in RHCS5 we do not generate the metrics if its value is
zero as a result the null value from that metric breaks the grafana
charts or graphs. This PR is to fix the above mentioned issue.
'ceph-volume raw list' is broken for a specific use case (rook).
rook copies devices from /dev/ to /mnt for specific/internal needs.
when ceph-volume raw list is passed a device from /mnt then
ceph-volume ignores it and return an empty dict.
That prevent rook from creating OSDs properly.

mon: fix mds metadata lost in one case.
In most cases, peon's pending_metadata is inconsistent with mon's db.
When a peon turns into leader, and at the same time a active mds stops,
the new leader may flush wrong mds metadata into db. So we meed to
update mds metadata from db at every fsmap change.
This phenomenon can be reproduce like this:
A Cluster with 3 mon and 3 mds (one active, other two standby), 6 osd.
step 1. stop two standby mds;
step 2. restart all mon; (make pending_medata consistent with db)
step 3. start other two mds
step 4. stop leader mon
step 5. run "ceph mds metadata" command to check mds metadata
step 6. stop active mds
step 7. run "ceph mds metadata" command to check mds metadata again
