Retry HTTP/2 REFUSED_STREAM errors automatically #6700
Description
The specs suggest it's safe to do so
- The REFUSED_STREAM error code can be included in a RST_STREAM frame to indicate that the stream is being closed prior to any processing having occurred. Any request that was sent on the reset stream can be safely retried.

Nginx can be configured to send this on old-enough connections:
Sets the maximum number of requests that can be served through one keep-alive connection. After the maximum number of requests are made, the connection is closed.
Closing connections periodically is necessary to free per-connection memory allocations. Therefore, using too high maximum number of requests could result in excessive memory usage and not recommended.

And our users are otherwise going to do it manually.
Is there an option (we may have missed) so OkHttp takes care of this transparently to the application?

We need a limit on how many automatic retries to attempt; maybe 1. Such retries should be on a different connection.
