This series adds blockdev-add support for NFS block driver.

Patch 1 helps to prepare NFS driver to make use of several runtime_opts
as they appear in the URI. This will make NFS to do things similar to
the way other drivers available in the block layer do. It also adds support
to handle new option "server".

Patch 2 helps to allow blockdev-add support for the NFS block driver
by making the NFS option available.
