gluster: IPv6 single stack support
Summary:
- This diff changes all locations in the code to prefer inet6 family
instead of inet. This will allow change GlusterFS to operate
via IPv6 instead of IPv4 for all internal operations while still
being able to serve (FUSE or NFS) clients via IPv4.
- The changes apply to NFS as well.
- This diff ports D1892990, D1897341 & D1896522 to the 3.8 branch.
Test Plan: Prove tests!
