[PATCH rfc 6/6] nvme-fabrics: expose support for traddr as dns names to userspace

[Sagi Grimberg]

userspace needs to know that the kernel is capable of doing a dns
query, so expose a custom opt called "dns_ip_traddr" which is not
an argument, but rather indication of support for dns names for
ip based traddr.
