    s390 FC device path fix for Ubuntu

    This fix solves a LUN attachment error for Ubuntu on s390 host setups. Fiber
    Channel requires a path for discovery of new devices, and Ubuntu uses a
    different format than previously assumed. This can be solved by simply adding
    the Ubuntu-style path to the list of possible paths, since they get quietly
    dropped if they lead nowhere in FibreChannelConnector._get_possible_volume_paths
    anyways.

Fix proposed to branch: stable/newton
Review: https://review.openstack.org/422279

This issue was fixed in the openstack/os-brick 1.10.0 release.

Ubuntu SRU details:

[Description]
The connector at os_brick/initiator/connectors/fibre_channel_s390x.py is supposed to also attach LUNs created with ubuntu running as OS on s390. The support for this functionality is as of yet not complete.

[Testcase]
Run devstack on a ubunto on s390 host, and create a volume with the 'openstack volume create'.
Expected result: A LUN should be made available.

[Regression Potential]
Low. The newton patch is an unchanged cherry-pick from the stable/newton upstream branch. The mitaka branch is also cherry-picked from the stable/newton branch, and required some modifications due to code existing in different files in mitaka.
