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-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.

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.

This commit does a couple of things:
* Avoid code duplication
* Clarify the code
* add more unit tests
* add myself to the author of the module
