If a service gets redeployed, it will stop and start a bunch of workers.

For each worker that's restarted it will ECONNRESET the socket and kill some inflight RPCs.

The circuit breaker immediately kicks in and things there is something wrong with the service.

We should ensure that we can do a rolling restart of all instances of a service without the circuit breaker penalizing all the caller.
