With the current design, kubernetes is not in a one-to-one relationship with PDP Subgroups.  This causes issues with respect to spinning up new PDPs.  For example, kubernetes may spin up additional PDPs due to excessive load, but PAP may assign them to a low-load PDP Subgroup.

To resolve this, the design should be changed so that kubernetes is in a one-to-one relationship with PDP Subgroups.  However, this would entail classifying the PDPs in some way so that PAP knows to which PDP Subgroup they should be assigned.  PDPs in different kubernetes clusters could report different PDP types (e.g., drools-type1, drools-type2) or they could report different supported policy types.

In addition, we need to resolve how hierarchical policy types are handled with respect to the "supported policy types".
