kv/RocksDBStore: Add CompactOnDeletion support

This commit adds support to compact column families when a certain number
of tombstone entries have been observed within a certain sliding window
during iteration.  It only helps when itereating over entries already in
SST files and not when iterating over ranges in memtables.

Likely we will still need to provide a mechanism to flush memtables and
compact column families once a certain number of rmkey or rm_range_key
calls are made.

ceph-volume: quick fix in zap.py

only if `--destroy` is passed in order to remove vg and pv when there's
nothing left.

With old deployments, it is possible that a lv_uuid matches more than 1
PV.
Given that `get_single_pv()` is only needed when `--destroy` is passed,
let's move this call where it is actually needed.

cephadm: mount host /etc/hosts for containers in podman deployments

Podman messes with the /etc/hosts file in certain version. There
was already a past issue with it placing the container name
there fixed by https://github.com/ceph/ceph/pull/42242. This time
it is adding an entry for "host.containers.internal" (seems to be
podman 4.1 onward currently). Iscsi figures out the FQDN for a
host by running

python3 -c 'import socket; print(socket.getfqdn())

which is resolving to "host.containers.internal" when run in
the container with the podman modified /etc/hosts.

There is also an issue with grafana dashboard with
this entry present

Passing --no-hosts resolves this, but I think in the past
we avoided that due to not wanting to break deployments
where host name resolution was handled using /etc/hosts.
That's why we had that workaround previously linked. This
time I'm not sure such a workaround exists. The try here
is to mount a copy of the host's version of /etc/hosts
into the iscsi container. That copy won't have the extra
entry podman adds in but will have any user created entries in
case they were actually using it for host name resolution.
If /etc/hosts file isn't present for whatever reason, we're
assuming that this user isn't using /etc/hosts for hostname
resolution, and just going back to passing --no-hosts.
