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 PR also allows the client to be used as a context manager, which will automatically clean up after itself rather than having to wait til process exit. This fixes issue kubernetes-client#1037, where the API client could hang indefinitely at garbage collection.

could you add a test that can run successfully with this fix, and would fail without the fix? |

cleanupfunction is registered with theatexitmodule.This PR also allows the client to be used as a context manager, which
will automatically clean up after itself rather than having to wait til
process exit.
This fixes #1037, where the API client could hang indefinitely at
