I am seeing errors "Exception occured; type <type 'exceptions.TypeError'> message Got an unexpected keyword argument 'async' to method get_namespaced_custom_object"

@johnugeorge the reason is because of the PR #790 update the python Kubernetes lib to 7.0.0
and it changed the parameter async to async_req.
The PR has been merged, we can try the test again.

@johnugeorge I think you can try to rebase the git branch, apply your commit to the master and git push again.
