Adapt the list of ceph packages for SUSE

SUSE needs more than one distro package for rados support. If
they aren't installed, issues like this [1] appear.

Sadly, the current variable expects only one package name,
and not a list of packages.

This change does the minimum job to make it work, simply
renaming the internal variable (renaming package with
packageS) for readability purposes, and using this new
variable as a list in the provided ``vars/main.yml``.
