protocol: Added iatt conversion to older format
Added iatt conversion to an older format, when dealing with
older RPC versions. This enables iatt structure conformance
when dealing with older clients.
This helps fix rolling upgrade from 3.x versions to 4.0 version
of gluster by sending the right iatt in the dictionary when DHT
requests the same.
