Leave xacml-pdp REST server always running
Liveness checks depend on the xacml-pdp REST server being available.
However, the REST server is only running when PAP puts it in an active
state. Modified the code to always leave it running.
In a subsequent review, we should split the healthcheck REST service
onto its own port so it can be left running, while the other services
are started/stopped in response to PAP active/passive requests.
