// Repeat while pending actions remain to be processed:
//   1. Gather as many actions as can fit in the request size limit. If we
//    encounter stale actions that should be erased, set those aside.
//   2. Increment upload_attempt_count for each action to be uploaded. Write
//    these actions back to the store and erase actions that should be erased.
//   3. Try to upload the batch of actions. If the upload is successful, get
//    the new consistency token and erase the uploaded actions from the store.
//
// If we have a new consistency token, it's the caller's responsibility to write
// it to storage.
