update api version controller

[dan wendlandt]

The API returns information about currently available versions when a tenant queries "/":

curl -H "Content-type: application/json" http://localhost:9696/
{"versions": [{"status": "CURRENT", "id": "v1.0", "links": [{"href": "http://localhost:9696/v1.0", "rel": "self"}]}, {"status": "PROPOSED", "id": "v1.1", "links": [{"href": "http://localhost:9696/v1.1", "rel": "self"}]}]}

This info is now out of date. v1.1 should be "CURRENT", and we very soon will need to add "v2.0" as "PROPOSED".
