What you expected to happen:
The configuration to load

How to reproduce it (as minimally and precisely as possible):
The GCP credentials expiration string has some decimal fraction of seconds specified in the time stamp. Then the following command fails.

import kubernetes as kube
kube.config.load_kube_config()

Specifically in kubernetes.config.dateutil the function parse_rfc3339 with the input 2020-02-06T01:10:34.194986955Z fails.

Anything else we need to know?:

Dumb fix (always results in 0)
dt[6] = int(float(groups[6]))

It should probably be converted to microseconds or something useful?
