In some circumstances a consul 1.4 client could be running in an
un-upgraded 1.3 or lower cluster. Currently this gives a 500 error on
the new ACL token endpoint. Here we catch this specific 500 error/message
and set the users AccessorID to null. Elsewhere in the frontend we use
this fact (AccessorID being null) to decide whether to present the
legacy or the new ACL UI to the user.
Also:
- Re-adds in most of the old style ACL acceptance tests, now that we are keeping the old style UI
- Restricts code editors to HCL only mode for all `Rules` editing (legacy/'half legacy'/new style)
- Adds a [Stop using] button to the old style ACL rows so its possible to logout.
- Updates copy and documentation links for the upgrade notices
* 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. There are various things tests that can just have intentions added
into them, like filters and such like, add intentions to these
2. Start thinking about being able to negate steps easily, which will
lead on to a cleanup of the steps
