Firestore Java SDK: java.lang.RuntimeException: ManagedChannel allocation site

[avertx]

Keep seeing this error randomly, what is the root cause? Filing bug report because this issue appears found/fixed perhaps in another codebase: googleapis/google-cloud-java#3648

I moved this issue from google-cloud-java to java-firestore.

@abramcat are you not calling close(), shutdown(), or something like that on some objects? See https://www.learngoogle.com/2019/06/10/firestore-errors/
