Adds support for ACL Roles and Service Identities CRUD, along with necessary changes to Tokens, and the CSS improvements required.
Also includes refinements/improvements for easier testing of deeply nested components.
1. ember-data adapter/serializer/model triplet for Roles
2. repository, form/validations and searching filter for Roles
3. Moves potentially, repeated, or soon to to repeated functionality
into a mixin (mainly for 'many policy' relationships)
4. A few styling tweaks for little edge cases around roles
5. Router additions, Route, Controller and templates for Roles

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
