This is a patch that adds a new LVM/nvmet job which also
exercises a few relevant code paths in os-brick
which are likely to be used in a production environment:
- Uses the new NVMe-oF connection information.
- Uses NVMe-oF native multipathing, even if it's by using the local IP
address, which is not real multipathing.
- Shares the namespace for all connections on the same node.
