feat(operator): automatically adopt generated resources

Automatically adopt resources generated by OLM during operator
installation. Any CSV installed via Subscription is adopted by an
operator named after the subscribed package and install namespace; other resources with
OwnerReferences or OLM-style owner labels referencing component CSVs are
transitively adopted.
