Description

By default Jetty Server only supports 200 threads.
On our daily use cases, we normally have more than 100 users on the single Zeppelin Server, which will create more than 200 threads in Jetty.

That could cause slowness or stuck because users could not receive WebSocket message.

Add configurable param feature to scale up the performance for Single Zeppelin Server whenever needs it
