Event Flow Interruption During Restart

[xmcqueen]

Analysis indicates that with the leaderElection activated, the interruption is about 17 seconds (the 15 second lease expiration period + 2 seconds for overhead). At high rates, that can be thousands of lost events. Certainly one option is to reduce defaultLeaseDuration, but I'd like it to be subsecond or even zero if possible.

I've been looking at the leader election code and I think we can get make that interruption interval much lower. I'm going to start working on that unless somebody has a better idea. I don't see a way to get the existing setup to go much faster than the defaultLeaseDuration.

Make sense, please go ahead 👍

This is working very well.

I found another source of missing events. I will try to get this all together and into a PR here soon.
