Record the engine's applicationId in KyuubiSessionEvent.

[wForget]

I want to record the applicationId of the engine in KyuubiSessionEvent, and then I will collect KyuubiServerEvent into elasticsearch so that I can quickly find the yarn application of the session.

How to get the applicationId in kyuubiServer？

1. If the new engine is created, we can get it in ProcBuilder.
2. If an existing engine is used, we can execute select engine_id() to get.

Good idea, and we can put it in TOpenSessionResp for both cases
