feat: Openshift compatibility

[micheelengronne]

Openshift needs to take over securityContext.

This PR creates a new value that disables security context handling by the chart.

Can you explain in more details why this is needed? It feels like this just needs a way to set securityContext to empty instead of adding a new option.

[micheelengronne]

It is a trick to avoid falling into helm/helm#12879 I agree we should be able to do by nullifying the securityContext but in case of using this chart as a subchart it doesn't work. With that mechanism we are immune against this bug.
