Add APPC LCM Interface

The LCM model code and service provider code is implemented.
This model code is now used for the vCPE use case scenario.

The vFW use case is still using the legacy APPC API as
request by APPC for Policy to use in R1. The APPC
service provider now generates a demo legacy APPC
request with pg-streams.

An A&AI named query is implemented for the vFW use case.
The code for obtaining the generic-vnf.vnf-id is not
in use until we set up the A&AI simulator to work
without having cyclical depenncies inside the POMs.

JUnits for the vFW and vCPE use cases are now supported.
These JUnits test the complete flow of each scenario.

A&AI testing is not supported in the JUnit test yet.
These JUnits use a target type of VM as VNF is not
supported yet. This will be changed when the Target
Lock supports VNF.

Amended to fix Sonar blockers.
