doc/radosgw: Improve language and formatting in config-ref.rst

The "Topic persistency settings" section includes convoluted
and incomplete sentences so attempt to improve the
language. The section lacks context so add a link to the
relevant documentation about Notifications.

The "Garbage Collection settings" note includes a sentence
that looks incomplete so try to improve the language.

Don't capitalize "Ops" in "RGW Ops" especially when the
same sentence talks about "op queue" with lower case "o".

Also improve formatting: indentation of a note and wrap
several very long lines.

build: install-deps.sh installs system boost on Jammy

Since on Jammy system boost is new enough for Quincy and we don't have
Jammy packages for older boost (we only have those for Focal), just
install the system packages rather than fetching ceph-libboost.

No analogous commit exists in main as while main's Jammy case installs
ceph-libboost, we just need a system package here.

build: Remove old ceph-libboost* packages in install-deps

Here, we extract `clean_boost_on_ubuntu()` and call it before other
installs on Debian distributions so that if we install a system boost,
a potentially newer `ceph-libboost` won't get in the way.

As the sources.list.d being removed in the original cleanup code isn't
the one we're currently installing in the install code, add a removal
for the currently used source, then do apt-update so packages from the
removed source are no longer included as available.

Two subsidiary dev packages from conflicting boost libraries can be
installed, but it leaves apt in an inconsistent state. To clean this
up, add `--fix-missing` to the removal line and call
`clean_boost_on_ubuntu()` before other uses of apt.

mon: block osd pool mksnap for fs pools

Commit 23db15d5c2b disabled pool snaps for the rados mksnap path. But
ceph osd pool mksnap was an alternate way that pool snaps could be
created.
This commit disables pool snaps via this alternate path as well.

NOTE:
Pool-level snaps and fs-level snaps can't co-exist since snap IDs are
likely to clash between the two different mechanisms and can result in
unintentional data loss when either of the snaps are deleted.
