split of rados-storage interface to mail data storage and mail metadata

  ima: save all immutable metadata in single xattribute 
- added new configuration options (ceph): 
  rbox_metadata_storage=ima | default
  rbox_storage_metadata_attr=ima
- added new unit tests to eval read/write of single attribute

setting rbox_metadata_storage=ima with the rmb tool will enable single attribute storage.
You can define the name of the attribute with the configuration parameter:
rbox_storage_metadata_attr=ima

adding attributes to the list rbox_updateable_attributes=BFK and enabling rbox_update_attributes=true will save the updateable metadata in separate attributes to allow faster updates.
