Fixing errors in rgw playbook for Trusty

- We don’t need ceph-extra for trusty
- Enable multiverse repo for access to libapache2-mod-fastcgi
- Update cache before attempting to install packages to register
multiverse repo and only refresh cache once an hour to avoid delays in
the playbook
- Add wildcard to disabling default site as on Ubuntu it is 000_default
by…default
