feat(controller): bump controller API to v1

PRs blocking this from being merged: #2136, #2159 and #2183. API documentation will be supplied in v0.15.

fixes #1042
This is to test the "accounts" page in the web UI: controller/web/templates/web/account.html still refers to this
```
  <form method="post" action="{% url 'rest_framework:logout' %}">
```
I think we should remove that from the web template then, or update it to the `v1` url mapping.
