Extract LocalContrailnetworkRepository interface.

This change extracts the old hnsManager logic as a separate adapter. It
brins us closer to pure core/driver module.

hnsManager package used to be responsible for creating HNS networks that
are associated with Contrail subnets.

Packaging:
* Create adapters/secondary/local_networking
* Create adapters/secondary/local_networking/simulator. Simulated HNS
and related code can be implemented there.
* Move everything under adapters/secondary/hns to
adapters/secondary/local_networking/hns - this is the actual HNS
implementation

Tests:
* Move old hnsManager integration tests to hns_test package, and
subsequently into the same hns_test.go file. This is because ginkgo
can't handle multile *_test.go files in the same package, it seems.
