    Add missing trunk segment type option for profile create

    The Cisco N1K plugin allows for 'trunk' type network profiles to
    be created in addition to existing 'vlan' and 'overlay' types.
    This fix is to add to the segment_type choices in forms.py to
    include the missing 'trunk' choice. Additionally the description
    message has been updated to make sure strings are uniform in all
    locations. The help string for the multicast range has also been
    updated to reflect a valid mcast IP and finally new unit tests
    have been added.
