Description

As discussed on mailing list dev@z.a.o subj "improving matplotlib integration in zeppelin" - in order to complete ZEPPELIN-1344 and give ability for one Python paragraph to update content in another one - we can use AngularDisplay system, same as in Apache Spark interpreter.

So without rerun another paragraph, it's possible to update result of a
paragraph from another.
Any interpreter can get AngularObjectRegistry[3] from InterpreterContext
[4], and AngularObjectRegistry allows create object / add event hook to
communicate with front-end.
