Make autocomplete request performant ## What does this MR do? Restricts the `autocomplete_sources`action to returning the `json`of one specific `at` type at a time. Makes sure all commands start by immediately showing the `loading` dropdown. If the `loading` dropdown is active, we will request and load in the data for that specific `at` type. We manually trigger the filter again. This time, if `loading` dropdown is not active, initiate default filter behaviour and use the correct data template. Also fixes an issue where `setup` was called multiple times by only setting up and destroying atwho on a focused/blured input. ## Are there points in the code the reviewer needs to double check? ## Why was this MR needed? `autocomplete_sources` was requested on page load and is large. ## Screenshots (if relevant) 3 requests for 3 different first-time references.  ## Does this MR meet the acceptance criteria? - [x] [CHANGELOG](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/CHANGELOG) entry added - [ ] [Documentation created/updated](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/development/doc_styleguide.md) - [ ] API support added - Tests - [x] Added for this feature/bug - [x] All builds are passing - [x] Conform by the [merge request performance guides](http://docs.gitlab.com/ce/development/merge_request_performance_guidelines.html) - [x] Conform by the [style guides](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/CONTRIBUTING.md#style-guides) - [x] Branch has no merge conflicts with `master` (if it does - rebase it please) - [x] [Squashed related commits together](https://git-scm.com/book/en/Git-Tools-Rewriting-History#Squashing-Commits) ## What are the relevant issue numbers?

- Move the `Oauth2::AccessTokenValidationService` class to `AccessTokenValidationService`, since it is now being used for personal access token validation as well. - Each API endpoint declares the scopes it accepts (if any). Currently, the top level API module declares the `api` scope, and the `Users` API module declares the `read_user` scope (for GET requests). - Move the `find_user_by_private_token` from the API `Helpers` module to the `APIGuard` module, to avoid littering `Helpers` with more auth-related methods to support `find_user_by_private_token`
Finished up autocomplete_sources action and added frontend to fetch data only when its needed Added wait_for_ajax to specs Fixed builds and improved the setup/destroy lifecycle Changed global namespace and DRYed up loading logic Added safety for accidentally loading data twice Removed destroy as its not necessary and is messing with click events from a blur race condition Created AutocompleteSourcesController and updated routes Fixed @undefined from tabbing before load ends Disable tabSelectsMatch until we have loaded data Review changes
