This commit adds the `block_db_devices` option support to the
ceph_volume module.
passing a devices list in `dedicated_devices` will make ceph-volume
creating 1 vg using these devices to create block.db partitions for data
devices.

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.

In order to be able to retrieve udev information, we must expose its
socket. As per, https://github.com/ceph/ceph/pull/25201 ceph-volume will
start consuming udev output.

osds-per-device needs to be passed to run_command as a string.
Otherwise, expandvars method will try to iterate over an integer.

The batch option got recently added, while rebasing this patch it was
necessary to implement it. So now, the batch option can work on
containerized environments.

The command is run with --report first to see if any OSDs will be
created or not. If they will be, then the command is run. If not, then
changed is set to False and the module exits.

If this is set to anything other than the default value of 1 then the
--osds-per-device flag will be used by the batch command to define how
many osds will be created per device.

This adds the action 'batch' to the ceph-volume module so that we can
run the new 'ceph-volume lvm batch' subcommand. A functional test is
also included.
If devices is defind and osd_scenario is lvm then the 'ceph-volume lvm
batch' command will be used to create the OSDs.

This really isn't needed currently and I don't believe is a good
mechanism for switching subcommands anwyay. The user of this module
should not have to be familar with all ceph-volume subcommands.

This module uses ceph-volume to create OSDs. Currently
it only supports the 'lvm' subcommand and 'create'.
