> PortMappingIsolator currently does not keep track of whether it is the one that adds the ingress qdiscs and never cleans them up.
> The goal is to not interleave with other administrators on the system but try to clean up after ourselves reasonably. A few steps we can do to make it better:
> maintain a bool and initialize to be false. True means we think someone else on the system is using the ingress qdiscs.
> in create, if there are already ingress qdiscs, set the bool to true; otherwise, create them.
> in cleanup, after cleaning up after our last container, if there are other filters, set the bool to true and continue; however, if there are no other filters and the bool is false, clean up the ingress qdiscs. This way after a proper shutdown, the system is clean.
> in isolate, we repeat the same behavior as in create.
> Overall, this shouldn't do worse than the current behavior but try to safely clean up after ourselves.
