Move all Dockerfile samples to non-root user

Expected Behaviour

As an OpenFaaS end-user, I want to run all samples on my OpenFaaS cluster, even with the new non-root feature enabled.

Current Behaviour

$ minishift status
Minishift:  Running
Profile:    minishift
OpenShift:  Stopped
DiskUsage:  ERR of

perhaps this is related to the error state from the OpenShift isRunning check

The problem faced currently?

No problem, just an enhancement

There should be switch button at the bottom left corner of mission control where we currently show sc version. Which switches the color theme of mission control

If you want this feature to be implemented, give it a thumbs up reaction, so that we can determine which features are important to you.
