Bug Description

This is mainly for initiator zoning. During the delete/update sequence of removing a target wwpns for an initiator zone, if 'activate=True', the code first does a hard delete of the zone, and then a subsequent recreation. During the time in between the deletion and creation of the zone, the VM loses all access to the volumes disks.

Instead of a delete/create of the zone, will implement CLI to do a zoneupdate for addition or removal of target wwpns in a zone.

    Fix Cisco Initiator zoning updates

    Instead of current methodology of deleting and recreating zones in
    order to update WWPN members, changed logic to perform a zone_update
    to modify existing zonemembers for a given zone. Fix prevents targets
    from losing connectivity to initiators during an update.
