Bug Description

    Fix FC connection handling in the storwize driver

    Creating FC connections was not working due to several issues:

    1. The lsfabric command in the Storwize/SVC omitted the delimeter and so
    the output was not correctly parsed by the driver.
    2. In some cases comparisons of WWPNs were not case insensitive - ensure
    we compare lower-case WWPNs.
    3. If the host supplied extra information in the connector (e.g. iSCSI
    initiator name in case of an FC setup, or FC WWNNs/WWPNs in an iSCSI
    setup), the driver would try to make those host mappings on the storage
    too. This could lead into unwanted behaviour and confusing error
    messages (for example, in an FC setup reaching the maximum number of
    iSCSI mappings).

    In addition, unit tests weren't properly testing FC - instead they were
    always testing iSCSI due to an error in parsing extra_specs. This patch
    fixes that error and the unit tests as well.

    These changes must all be made together for unit tests to pass.
