3par driver leaves dangling LUNs after volume detach when iscsi & FC volumes used together

[Jay Mehta]

Configured both 3par iscsi & FC driver and attached both iscsi/fc volumes to instance running on same compute node.
When both ISCSI and FC attaches are made on the same compute host you are left with dangling LUNs after removing all attachments.
steps to reproduce:
Load iSCSi & FC 3par driver & enable multipath for iSCSI
1. Create iscsi & fc volumes
2. create one instance
3. Attach the FC volume first & iSCSI volume to instance same instance
4. check multipath -ll
5. detach the volume

    Implement match-set type 3PAR FC VLUN creation

    Creating match-set type FC VLUN, instead of host sees type.
    Passing node-slot-port details while creating a VLUN.
    This patch fixes dangling lun entry left when both ISCSI and FC
    attaches are made on the same compute host, after removing all
    attachments. Updated version number to 3.0.8.
    Updated broken unit test cases.
    Adding release note.
