What this PR does / why we need it:
Before this PR it was not possible to actually use nullable variables by setting them to null (in the YAML).

This PR makes the Value field nullable and makes sure the variable validation can handle it

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
