Mitigates hanging streams by detecting idle streams and reconnecting after a timeout (default 10min for partition assignment streams, 2min for all others).
The StreamIdleTimer is restarted when the client receives a response on the stream. The stream is reinitialized when the timeout expires. For publish and commit streams, the timeout will still expire even if there is no user activity.
Internal: cl/422650400 and subsequent fixes.
