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
Workaround on swiftclient errors (jiocloud/puppet-rjil#188)

This is a workaround to add content-type on apache if not there.
Added ceph mon timecheck interval configuration

This will help to detect the time difference quickly by ceph mon.
Used apache::vhost::custom_fragment to set the config.
