[DCAE] Svc template support for policy release override

As ONAP (and policy framework) can be deployed with any release name,
the policy sidecar must support releasename as configuration.
The releasename is important to identify the K8S secret
created by Policy Framework (for retreiving the username/password
config required by Policy-Sidecar container).
