Fix pool names in RadosGW charm

The latest Ceph versions forbid pool names that start with a dot.
Since the RadosGW charm uses pools named so extensively, this
patchset fixes that issue.

In addition, the Ceph libraries are synced as well, since they
were outdated.

(cherry-picked from commit 4bc1596)
