[CCSDK] Make a1policymanagement react on ConfigMap updates
Updated Deployment spec to template ConfigMap files in runtime allowing live reaction of application to config changes. Provided Configmaps with scripts to handle monitoring configmap-provided files. Updated envsubst to explicitly point to downloaded version. Issue-ID: CCSDK-2958 Signed-off-by: Konrad Bańka <k.banka@samsung.com> Change-Id: I22e18f2838c0956f899cb9fa96d9fd862e6c6942
