Remove direct DB Load/Save from apex-pdp

This review is part of a series of reviews to move the apex-pdp state
machine model to use the base model types in policy models.

Persistence of policies for apex-pdp is now implemented in PAP and API.
The historic direct load and save functionality for APEX policy state
machine models to and from databases is no longer used and no longer
supported.

This revmoves the DAO code from apex-pdp and the associated handling
and test code.

The next review will remove the JPA annotations.
Subsequent reviews will mvoe the mdoel across to use the policy models
base model types.
