Cluster and endpoint information should be cleaned up

[skitt]

What would you like to be added:

Some way to expire broker CRs which are no longer relevant.

Why is this needed:

Currently, clusters which stop running remain in the broker, which causes new clusters to try to set up tunnels to them, unsuccessfully. This includes previous incarnations of re-joining clusters, which means clusters can end up spending significant amounts of time trying to set tunnels up to themselves...

Makes sense, I'd propose a mechanism similar to :
https://github.com/submariner-io/submariner/blob/master/pkg/cableengine/syncer/syncer.go

https://github.com/submariner-io/submariner/blob/master/pkg/cableengine/syncer/syncer.go#L125

With a bigger TTL time

@skitt this one is one year old now. If it's important, let's prioritize for this/next sprint

We talked about this on the PR scrub today. It still seems important, and it seems related-but-different from the ongoing Uninstall Epic (submariner-io/enhancements#50). This is more about destroyed/missing clusters.

Closing in favor of submariner-io/enhancements#39, which tracks the same thing.
