Update code to comply with Gluon API Spec

Many changes to support new Gluon API Spec.

Summary of changes:
- gluon-api-tool: New command line tool to validate an API Model.
- Restructured models directory
  - Removed proton directory
  - Created a directory for the base objects file
  - Created directory for net-l3vpn and change filename to api.yaml
  - Created directory for a test API
- Updated manager code to automatically create default interface
  object when a port object is created.
- Updated shim layer code to track the interface object and to
  handle service binding to interface instead of port
- Added new API types and validation logic
- Updated API and Database generator code to process the new
  model constructs
- Updated the test cases to complete with the new model format.
- Reworked code to support parent/child API relationships.  The
  SubObjectController now works for one level.
