* Add some tests to check the correct GET API endpoints are called
* Refactor adapters
1. Add integration tests for `urlFor...` and majority `handleResponse` methods
2. Refactor out `handleResponse` a little more into single/batch/boolean
methods
3. Move setting of the `Datacenter` property into the `handleResponse`
method, basically the same place that the uid is being set using the dc
parsed form the URL
4. Add some Errors for if you don't pass ids to certain `urlFor` methods
1. Listing, filtering by action and searching by source name and
destination name
2. Edit/Create page, edits ping the API double fine, need to work through
creates and deletes
3. Currently uses a `Precedence` intention keyname that doesn't yet
exist in the real API
