Master may send `FRAMEWORK_UPDATED` for a new framework ID in operator API.

In the operator streaming API, the master only sends FRAMEWORK_ADDED if a framework is subscribed with no ID:

That means after a master failover, if a framework is recovered from an agent or subscribed with an ID, a FRAMEWORK_UPDATED with a framework ID that is previously unknown will be sent to the subscribers.
