    Deleting VM ports on cluster delete flow

    - modified delete port task to take a list of ports and delete all
      specified ports as well as taking a single port
    - delete port task also does not throw an exception upon failure to
      delete a port, it instead logs a warning
    - modified delete cluster flow to retrieve a list of ports for a VM and
      attempt to delete each port after deleting the VM
