operator: Add OperatorGroup queueinformer

Add a queueinformer for OperatorGroups since they are now an input to
resolution via the global catalog exclusion annotation. Namespace
resolution will be triggered on changes to an OperatorGroup, in case the
value provided on that annotation by the user changes.
