Make stand-alone Policy environment

This is a first cut at making it possible to easily run Policy
components within a stand-alone environment.  Made the following
changes:
- enhanced wait_for_port.sh to accept a list of hosts/ports
- enhanced wait_for_port.sh to accept an optional command to execute
  when the wait completes
- consolidated all of the yml files into a single file
- removed "extra" services from the yml so that a component and its
  dependents can be brought up in a single invocation
- modified the component setup.sh

With these changes, a developer can clone the csit repo, run detmVers.sh
to set the docker image version env variables, and then bring up a
component (and its dependents) using:

  docker-compose -f scripts/policy/docker-compose-all.yml
    up --detach <component>

Note: this does not preload or deploy any policies; that must be done
manually via curl.

Modified to use new simulator docker image.
Also fixed drools-apps CSIT broken due to disabling frankfurt
controller.
Also removed operational.Apex policy. The csar file used in
policy-distribution test is also updated to reflect this change.
