Highstreet Contribution integration

After cloning Highstreet repo, https://github.com/highstreet-technologies/transportpce/tree/stable/aluminium, rebase the code on stable Phosphorus. After the code is rebased, propose Highstreet to push the code on their Github site, and ask them how they want to proceed to push the code on TransportPCE Gerrit.
The goal is to have in our latest distribution all the code that has been modified in transportPCE to provide FCPS in ONAP. This includes the modifications done in the Renderer, Common and Network model module. For what concerns ODL Client feature, the code might be pushed somewhere else by Highstreet to make it available for consumption (as a library?) by transportPCE.
Acceptance criteria : the rebased code is available to Highstreet, and the decision on how to make it available on transportPCE Gerrit is validated by both parties.

WARNING : need to take care about ONAP CCSDK dependencies
