When running rhel8 containers on a rhel7 host, after zapping an OSD
there's a discrepancy with the lvmetad cache that needs to be refreshed.
Otherwise, the host still sees the lv and can makes the user confused.
If user tries to redeploy an OSD, it will fail because the LV isn't
present and need to be recreated.
ie:

ceph-volume recently introduced a breaking change because of a `lvm
batch` refactor.
when rerunning `lvm batch --report --format json` on existing OSDs, it
doesn't output a valid json on stdout.

Running the `ceph_crush.py`, `ceph_key.py` or `ceph_volume.py` modules in check
mode resulted in the following error:
```
New-style module did not handle its own exit
```
This was due to the fact that they simply returned a `dict` in that case,
instead of calling `module.exit_json()`.

When using the lvm batch ceph-volume subcommand with dedicated devices
for filestore (journal) or bluestore (db/wal) then the list of devices
is convert to a string instead of being extended via an iterable.
This was working with only one dedicated device but starting with more
then the ceph_volume module fails.

On containerized deployment, the OSD entrypoint runs some ceph-volume
commands (lvm/simple scan and/or activate) which perform badly without
the ulimit option.
This option was added for all previous ceph-volume commands but not on
the ceph-osd container startup.
Also updating hard limit value to 4096 to reflect default baremetal
value.

The ceph nodes couldn't have the python six library installed which
could lead to error during the ceph_volume custom module execution.
ImportError: No module named six
The six library isn't useful in this module if we're sure that all
action variables passed to the build_ceph_volume_cmd function are a
list and not a string.

The ceph-volume lvm list command takes ages to complete when having
a lot of LV devices on containerized deployment.
For instance, with 25 OSDs on a node it takes 3 mins 44s to list the
OSD.
Adding the max open files limit to the container engine cli when
executing the ceph-volume command seems to improve a lot thee
execution time ~30s.
This was impacting the OSDs creation with ceph-volume (both filestore
and bluestore) when using multiple LV devices.

If you deploy with 2 HDDs and 1 SDD then each subsequent deploy both
HDD drives will be filtered out, because they're already used by ceph.
ceph-volume will report this as a 'strategy change' because the device
list went from a mixed type of HDD and SDD to a single type of only SDD.
This situation results in a non-zero exit code from ceph-volume. We want
to handle this situation gracefully and report that nothing will be changed.
A similar json structure to what would have been given by ceph-volume is
returned in the 'stdout' key.
