Right now we use a simple 10-second retry rule: https://github.com/realm/realm-object-store/blob/v10/src/sync/sync_session.cpp#L284

This is suboptimal in a number of scenarios:

• In case there is a persistent error, e.g. if the user has been disabled on the server.
• If the device is offline.

Suggested changes:

1) Use some form of exponential backoff to avoid draining the battery

2) Log that this is happening, see https://github.com/realm/realm-object-store/issues/1037

3) Hook into `SyncManager::shared().reconnect()` so calling this will also reset the the timer in 1)
