Loading configuration file fails when insecure-skip-tls-verify is false

[ganchurin]

What happened:
Loading configuration file with config.load_kube_config() failed with the following error:

Traceback (most recent call last):
  File "TestK8Client.py", line 4, in <module>
    config.load_kube_config()
  File "/usr/local/lib/python2.7/site-packages/kubernetes/config/kube_config.py", line 649, in load_kube_config
    loader.load_and_set(config)

  File "/usr/local/lib/python2.7/site-packages/kubernetes/config/kube_config.py", line 499, in __getitem__
    % (key, self.name))
kubernetes.config.config_exception.ConfigException: Invalid kube-config file. Expected key insecure-skip-tls-verify in [EDITED]/.kube/config/{'cluster': {'insecure-skip-tls-verify': False, 'certificate-authority-data': [EDITED], 'server': [EDITED]}, 'name': [EDITED]}/cluster

How to reproduce it:
The configuration file must include the following lines:

clusters:
- cluster:
    insecure-skip-tls-verify: false

Anything else we need to know?:
Java-client works fine with the same configuration file.

Environment:

• Kubernetes version: v1.11.8
• OS: MacOS 10.14.6
• Python version: 2.7.13
• Python client version: 10.0.1

I can reproduce this issue with v10.0.1. Interestingly having insecure-skip-tls-verify: true works fine. I think there is something wrong in the getter

@roycaihw The corresponding PR was merged. Do I correctly understand that now I should propagate changes from python-base into python repository? Thanks!

[roycaihw]

Yes, please open a PR to update the python-base submodule, e.g. #911

[ganchurin]

Already done in #969
