Python script for installing kubernetes helm.
The script calls the Github API to find the latest release of helm, downloads
the .tar.gz archive from Google Cloud storage, extracts the helm binary
into the location specified and makes it executable by the current user.
Currently requires Python 3.6+ due to use of f-strings.
It uses only modules from the python standard library.
$ python3 get_helm.py /usr/local/bin/helm
