rgw: handle deep uri resources

Browse Source 
In case of deep uri resources (ones created beyond a single level
of hierarchy, e.g. auth/v1.0) we want to create a new empty
handlers for the path if no handlers exists. E.g., for
auth/v1.0 we need to have a handler for 'auth', otherwise
the default S3 handler will be used, which we don't want.
