Add CRD adoption hook

[fhielpos]

In order to install the PolicyException CRD from the policy-meta-operator app, we need to add some labels and annotations to it. Since KPO owned it, this would be the best place to do it.

I'm fine with this but I wonder how sure the upgrade path is. How likely is it that a cluster has the CRD already, but won't update KPO again prior to trying to install PolMO?
Would this logic work as a pre-install hook on PolMO?

All clusters will need to update KPO to make it work with policy-meta-operator. The CRD would exist in every cluster that already exists. We can make POLMO depend on KPO for now as a solution to avoid POLMO inconsistencies but I want to see how bad it breaks.

Would this logic work as a pre-install hook on PolMO?

I tried, but no, Helm will template the chart and identify that the CRD is already present before even running the hooks.

Fine with me. This means there will be a required bundle version or range before going to PolMO. I know of at least one customer who has KPO disabled currently, so we'll have to do some communication
