Do not install additional CentOS packages via ceph-ansible

EPEL is required by the Ceph RPM repo maintained at ceph.com but
not by the CentOS SIG repo. The other packages should be already
installed in the infra image.

This change overrides the list of required packages in ceph-ansible
so that it does not install epel-release nor additional unneeded
packages [1].
