core: Feature added to accept CidrIp in auth.allow
Added functionality to gluster volume set auth.allow command to
accept CIDR IP addresses. Modified few functions to isolate cidr
feature so that it prevents other gluster commands such as peer
probe to use cidr format ip. The functions are modified in such
a way that they have an option to enable accepting of cidr
format for other gluster commands if required in furture.
