Description

ZEPPELIN-1345 updates Python `PyZeppelinContext` and Pyspark `PyZeppelinContext ` but does not touch Python `Py4jZeppelinContext` - wich is used for dynamic forms, in case py4j is installed on the system for things like

z.select("Choose a letter", ([a,"a"], [b,"b"], [c,"c"]))

In latter case Python interpreter becomes not useable - any line results in

x = 1

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Py4jZeppelinContext' object has no attribute '_displayhook'
