There's 2 properties (`zeppelin.server.rpc.portRange` and
`zeppelin.interpreter.rpc.portRange`) that could be used to constrain the
portRange of zeppelin server rpc and interpreter process rpc. And user can
config these 2 properties to use a fixed port so that user can just expose this
fixed port on containers. @Leemoonsoo Is this what you concern ?---
