* [python] Cleanup ThreadPool with atexit rather than __del__
This removes the `__del__` function from the generated Python client,
and replaces it with a `cleanup` function. When a ThreadPool is created,
the cleanup function is registered with the `atexit` module.
This fixes#5093, where the API client could hang indefinitely at
garbage collection.
* Update petstore examples
* Test to ensure threadpool is cleaned up
* Docs now encourage using the context manager
* Regenerate docs
* Update samples
* 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
The linting results for the generated samples are as follows
where the first number is the BEFORE and the second is AFTER.

Enforces linting for python clients by running flake8 for the generated
python client.
