Native policies support in docker

Depends on https://gerrit.onap.org/r/#/c/policy/docker/+/101758/
for package cleanup.

The work is needed to run the PDP-D with no applications, native
policies may exercise this set up.   This work provides a functional
image with a precooked installation.

This work will allow fixing and cleaning up of CSITs specific to
this repo which maintenance is problematic.
