WIP: zuul: Test LVM/nvmet additional job

This is a patch that adds a new LVM/nvmet job similar to the one we
added before, but in this case we test a completely different
configuration to exercise different code paths in os-brick:

- 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.

NOTE: Since it's a WIP patch all other check jobs have been removed.
