container: move lvm2 package installation

Before this patch, the lvm2 package installation was done during the
ceph-osd role.
However we were running ceph-volume command in the ceph-config role
before ceph-osd. If lvm2 wasn't installed then the ceph-volume command
fails:

error checking path "/run/lock/lvm": stat /run/lock/lvm: no such file or
directory

This wasn't visible before because lvm2 was automatically installed as
docker dependency but it's not the same for podman on CentOS 8.
