Fixes two bugs with degraded health checks: 1) When an active health check succeeded but marked the host as degraded, we'd always set the change_state to ChangePending, which meant we'd not ever invoke the callback when hosts went from healthy -> degraded. 2) Fix typo preventing degraded hosts from being updated on worker threads.

I couldn't find a good place to add a test for this - any ideas?

I think you should be able to add a test in cluster_manager_impl_test that does a sequence of updates and then verifies that the thread local host sets have the hosts they should?
