first part of changes for OpenShift compatibility - #757

Proposed changes

Current Lowcoder images cannot run in Openshift Container Platform because they expect to be running as root which is not true for OpenShift. Openshift automatically starts all container at a RANDOM non-privileged user id

These changes are not complete - for full Openshift compatibility a lot more needs to be changed - will be discussed in #616. These changes are the "easy" ones that will not need updates or changes inside your current setup (should be non-breaking)

Additionally some linting of existing code was done to be more posix compliant.
