Fix issues with drools pdp of policy framework

Https does not seem to be working in the policy framework, hence changed it to http.
All other components of the framework are also using http.

The following REST call succeeds now that shows the health of drools along with other components:

curl -k -u 'healthcheck:zb!XztG34' -X GET "https://localhost:6868/policy/pap/v1/components/healthcheck"

{"pdps":{"xacml":[{"instanceId":"policy-xacml-pdp","pdpState":"ACTIVE","healthy":"HEALTHY"}],"drools":[{"instanceId":"drools-apps","pdpState":"ACTIVE","healthy":"HEALTHY"}],"apex":[{"instanceId":"policy-apex-pdp","pdpState":"ACTIVE","healthy":"HEALTHY","message":"Pdp Heartbeat"}]},"healthy":true,"api":{"name":"Policy API","url":"https://policy-api:6969/policy/api/v1/healthcheck","healthy":true,"code":200,"message":"alive"},"pap":{"name":"Policy PAP","url":"https://policy-pap:6969/policy/pap/v1/healthcheck","healthy":true,"code":200,"message":"alive"}}
