Adjust helm chart to runAsNonRoot

[domi2120]

Description

Currently the helm chart does not set a podSecurityContext. This may prevent the use in kubernetes clusters which do not allow images that run as root for security reasons.

The Container already uses a non root user, so setting runAsNonRoot and specifying the User/Group ID (because runAsNonRoot requires a numeric user for validation) is sufficient. This allows the use in kubernetes clusters which do not allow images running as root.

Hi @domi2120 - thanks for the contribution/it makes sense.

cc: @mindovermiles262, @aduss-storable & @MindTooth who added & tested our initial helm chart support. I'll merge this soon unless I hear otherwise.

We need to merge #1589 too.
