Add openstack-helm-plugin git repository

This repository will contain the code of the
OSH Helm plugin which provides some convenience
for end users while deploying Openstack using
OSH Helm charts.

Helm allows installing plugins from git repos but
it assumes cloning the whole git repo to the user's machine.
To avoid this we create this separate repository which
will contain only the plugin code.
