feat(cloudnative-pg): clusterrole aggregated to user facing roles

[jouve]

create rbac to view/edit cnpg crds and aggregate to user facing roles

view/edit/admin clusterroles are bound to a user & namespace, to manage said namespace, and now allow to create a cluster/backup/etc with this change.

Can you remove the bump to the version? Otherwise looks good to me, thanks for switching to false by default 🙏

Is this still relevant or should we close it?
