This PR adds a non-assertive test which helps expose data races by doing a lot of concurrent write operations on a single ManagedStream instance. As a byproduct, this cleans up two possible races: In the first, a deferred function may incorrectly access a retained context. We change this to grab a reference to the context in the defer where we still retain the lock. In the second, the retry mechanism leverages math/rand and retry processing can yield concurrent usage of the random number source. PR adds a mutex guard to the source. Fixes: googleapis#9301
