Radosgw port from upstream (WIP)

Some comments (like 'this is from file XY") are for review only, will be removed


Depends on https://github.com/crowbar/barclamp-ceph/pull/56
According to this documentation part 
http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html#fcgidfixpathinfo

I think that it can be removed
