This commit implements the new tables for VPN endpoint-groups, and the
CRUD REST API. Validation logic has been added for the reference
implementation. Migration files are created, so that the needed tables
are created. Unit tests have been added for the API and database.
The neutron client and Horizon support for this new API will be handled
separately, as will API test cases for the new API.
This new API is a prerequisite for providing the multiple local subnet
feature, which will use this API and make changes to existing APIs. At
that time, migration and backward compatibility support will be provided,
so that users can migrate smoothly to the new API (since there is no
support for micro-versioning).
