Description

InterpreterContext is passed to methods in Interpreter.
Also singleton thread local instance is provided for any 3rd party library.

Currently, the only Zeppelin Interpreter print output to the front end is returning InterpreterResult from interpret() method.
For ZEPPELIN-554, there should be another way to send output to the front-end, in streaming way.
