[firebaseMessaging] Automatic retry logic for topic subscriptions.

[t-yasukawa]

Please tell me about the behavior when subscribing (or unsubscribing) by topic fails.

Q1. If it fails, the subscription is automatically retried. Is it possible to cancel it? I want to tell the user that the subscription has failed and cancel the subscription.

Q2. If it fails, the subscription is automatically retried. Is there a maximum limit of retries?

Q3. If it fails, is the order in which multiple retry processes are executed guaranteed?

ex)
step 1. firebaseMessaging.unsubscribeFromTopic ("Topic1")
step 2. firebaseMessaging.subscribeToTopic ("Topic2")
step 3. firebaseMessaging.unsubscribeFromTopic ("Topic2")
step 4. firebaseMessaging.subscribeToTopic ("Topic1")

[Run]
step1 retry ... complete.
step2 retry ... error.
step2 retry ... error.
step2 retry ... complete.
step3 retry ... complete.
step4 retry ... complete.

[Answer]
Topic1 is subscribed.
Topic2 is unsubscribed.

thank you.
