addNotice in controller class doesn't match API used by local python interface

[bpaauwe]

The addNotice API in the cloud interface is:
def addNotice(self, data):
while in the local interface it is:
def addNotice(self, data, key=None):

Code written to make use of the 'key' parameter that works correctly with local polygot fails when running on cloud polyglot

Looks like currently the polyinterface addNotice() will handle a string message (value) with an optional key, a dictionary with a key and value (msg), or a list of dictionary objects. The pgc_interface addNotice() errors out on anything other than a dict.
