Radosgw work and refined some stuffs in ceph

1. Made radosgw working with latest versions
2. Refined ceph::auth
3. Removed http config template and used apache::vhost instead
4. Added workaround for swift errors (jiocloud/puppet-rjil#188)
5. Configured mon timecheck interval to quickly detect time difference
apache::vhost takes a $custom_fragment argument that you can use for this instead. That's better than relying on a knowing what the $target value should be for concat::fragment.
