extend vnf properties model for cds actors

CDS operations for VNFs default to vFirewall-like behavior for
AAI queries where vserver and target resources are required.

The properties refactoring allows for enriched
vnf-id behavior (similar to vCPE) and provides some leg work
for other extensions.

Fix dmaap simulator sporadic test errors in junits
