Trailing slash on kube/config causes failures.

[karlbunch]

Using the example1 code if your ~/.kube/config has an ending slash in the URL you get this failure:

Listing pods with their IPs:

If you remove the trailing slash in the config file it works fine. kubectl has no issue with the trailing slash.

Looks like just adding rstrip('/') here fixes it:

    def _load_cluster_info(self):
        if 'server' in self._cluster:
            self.host = self._cluster['server'].rstrip('/')
