Since juju-2.8.0 there is JUJU_DEPARTING_UNIT environment variable to
figure out what unit is being removed, so when `local_unit() ==
departing_unit()` is where the clean up should happen. The fix could
take advantage of this and provide a action (maybe?) that operators
running juju<2.8.0 would need to use to clean up ports.
