Helm install doesn't work in OpenShift container

[seansund]

The default behavior of a container that is run in OpenShift is to run under a randomly assigned uid that is part of the root group.

For a helm install of a chart in a helm repository, two things happen:

1. The helm repo index is downloaded into /root/.cache/helm/repository
2. The helm chart is downloaded into the current working directory - /config

For the helm install to work in an OpenShfit container, the root group needs to be able to read and write to the home and working directories.
