K8s at home migration - Githubissues

This PR imports several helm charts from the k8s-at-home repo, which was deprecated. They have been copied verbatim and received some tweaks:

Change maintainer to djjudas21
Change library chart from k8s-at-home/common to bjw-s/common (which was forked from k8s-at-home)
Bump version
