Subject: [PATCH 521/529] rpc: use address-family option from vol file
This patch helps enable IPv6 connections in the cluster.
The default address-family is IPv4 without using this option explicitly.
When address-family is set to "inet6" in the /etc/glusterfs/glusterd.vol
file, the mount command-line also needs to have
-o xlator-option="transport.address-family=inet6" added to it.
This option also gets added to the brick command-line.
Snapshot and gfapi use-cases should also use this option to pass in the
inet6 address-family.
