Adds a filter option to topologies to allow filtering out duplicate notifications.

Change checklist

[x] I have performed a self-review of my own code
[x] I have made corresponding changes to the documentation if necessary (this includes comments as well)
[x] I have added tests that prove my fix is effective or that my feature works

The registrar test suite has new should use a filter... tests that exercise the code paths, using a PeerFilter which has type overlap with TopologyFilter so I think we're good there.
