pin ceph packages to release o=Ubuntu on rocky/bionic

When you're installing ceph on ubuntu/bionic, the luminous release isn't
readily available from ceph.com, and you end up pulling mimic packages
from uca instead. Fortunately luminous packages are available in the
distro repo.

apt-cache policy examples;
uca: release o=Canonical,a=bionic-updates,n=bionic-updates/rocky,c=main,b=amd64
ceph: release o=ceph.com,a=stable,n=bionic,c=main,b=amd64
ubuntu: release v=18.04,o=Ubuntu,a=bionic-backports,n=bionic,l=Ubuntu,c=main,b=amd64
