From OpenShift 4.4 on the built-in SCCs will be managed and thus
you cannot any longer mutate them by adding user. The proper way
is either to copy an existing SCC or use RBAC to access them.

This updates the documentation for the RBAC approach.

x86_64 to latest Alpine

The arm images is switched to multiarch since the hypriot image hasn't been updated in 3 years:
https://hub.docker.com/r/hypriot/rpi-alpine/tags

Currently the multiarch release of Alpine 3.11 is hold back by QEMU issues, see:
multiarch/alpine#28 but the update to 3.10 is a huge leap and 3.10 is still under support :)
