libglusterfs: Implement cluster-syncop

Browse Source 
This patch implements syncop equivalent for cluster of xlators. The xlators on
which the fop needs to be performed is taken in input arguments to the
functions and the responses are gathered and provided as the output.

This idea is taken from afr-v2 self-heal implementation by Avati.
