More options for setting/overriding values

This merge request is about adding the options -f|--values as available with helm install (c.f. https://docs.helm.sh/helm/#helm-install)

Moreover the order of -f|--values|-s|--set|--set-string will be retained since later values override earlier ones.

So this should for example enable the possibility to specify default values using -f|--values and override selected values using -s|--set|--set-string.
