Remove deprecated Policy Component Tests

Remove deprecated Policy Component Tests

These tests I don't think are being called anymore. They refer to
the old policy/engine code which is being deprecated.

In addition, removing the drools-pdp Health check as the new PAP
component consolidates all the policy components into one Healthcheck
now.

Minor fix for dcagen2 Policy Type that was missed in my last review.

Renamed the Policy Healthcheck to remove the "new"
