Subject: [PATCH 512/517] glusterd: shared storage mount fails in ipv6
environment
Issue:
In case of ipv6 environment, the mounting of glusterd_shared_storage
volume fails as it doesn't recognises the ipv6 enviornment.
Fix:
In case of ipv6 environment, the address-family is passed
to the hooks script on creating shared-storage, then depending
upon the address-family --xlator-option=transport.address-family=inet6
option is added to the mount command, and the mounting succeeds.
>Fixes: #1406
