Pin REST API version v0.2 and start on REST API v0.3

Currently unit tests use the latest REST API version. However,
REST API version v0.3 will not copy the API of version v0.2.
This means the version v0.2 should be used for existing unit tests.

Also add a default router for REST API v0.3 to indicate that the
work started on it.
