[python-client] Add model default values (#1776)

* Adds two models to the v2.0 spec, uses examples as defaults in python client

* Adds array default and type_holder_default and type_holder_example tests

* Re-generated python security client with ./bin/security/python-petstore.sh

* Changes comment text, rebased master

* Updates client + server samples

* Adds missing samples updates

* Changes python client to look for true or false with booleans in toDefaultValue

* Changes boolean casting to use Boolean.valueOf

* Adds deserialization fix for python tests

* Changes Mock to namedtuple in python deserialization tests

* Actually remove unittest.mock
