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

Expected Behavior

When you click to the event source links, they should take you to the appropiate documentation

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

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

When dealing with multiple resources, one might often want to see 20/50/100 items per page rather than 10. Hence we should provide an option to the user to change the page size.

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.
