Add some math markup to some of the mathematical expressions in
doc/rados/operations/placement-groups.rst.
This change has advantages as well as disadvantages. On the one hand,
the mathematical expressions look nicer and are easier to read. On the
other hand, the rendered mathematical expressions are not searchable as
a part of the text, which makes CTRL+F searches useless in finding them.
This PR is offered as an RFC on the matter of whether mathematical
expressions should be rendered with the :math: extension.

Edit doc/operations/rados/pools.rst.
There remains confusion in this part of the document regarding pg_num
and pgp_num. pg_num and pgp_num are not explained with sufficient
clarity. A future commit will clear up this confusion. There is also
some potential confusion between on the one hand the strings "pg-num"
and "pgp-num" and on the other hand "pg_num" and "pgp_num". The strings
with the hyphens are used in dummy commands, and the strings with the
underscores are used as key names. I think it possible that this could
confuse a reader, but I am open to discussion on the matter.

Fix a link in doc/rados/configuration/common.rst that was missing its

This is a follow-up to PR: https://github.com/ceph/ceph/pull/48703.
This commit also considers changes made ephemerally using either the
'daemon' or the 'tell' interfaces to override the built-in mClock
QoS parameters. In such a scenario, the ephemeral changes are removed
using the rm_val() method exposed by the config subsytem and logging
this information.
Other changes:
1. Add a standalone test to exercise the fix.
2. Add documentation note on the outcome of the attempt to modify
built-in profile defaults.

This topic has been discussed many times; recently at the Dev
Summit of Cephalocon 2023.
This commit is the minial version of the work, contained entirely
within the `doc`. However, likely it will be expanded as there
were ideas like e.g. adding cache tiering back experimental feature
list (Sam) to warn users when deploying a new cluster.
