Use upstream LWRP ceph client

This is just a copy of upstream files. I do not see anything distribution specific, so I haven't made any changes.
According to https://github.com/escapestudios-cookbooks/composer/commit/106761238a81c9170873a4e152df37d988f98fb1 and https://github.com/opscode/chef/blob/807891d08dc5c436da237ec8a09639cea87a04fa/lib/chef/provider/lwrp_base.rb#L130 it should be safe to skip this line for us
