Copy policy-endpoints from drools-pdp to common
Removed policy-endpoints, and 3 classes from policy-core. Replaced refenences to the deleted classes with references to the corresponding classes in policy-common Issue-ID: POLICY-967 Change-Id: I547cde4894424b8f40b7ddd4e2342ebb729cb588 Signed-off-by: mmis <michael.morris@ericsson.com>
