Resolve "[Rails5] `ActionView::MissingTemplate` in spec/features/projects/wiki/user_views_wiki_page_spec.rb"

Repository archives are always named `<project>-<ref>-<sha>` even if
the ref is a commit. A consequence of always including the sha even
for tags is that packaging a release is more difficult because both
the ref and sha must be known by the packager.

- add `<project>/-/archive/<ref>/<filename>.<format>` route using the
`-` separator to prevent namespace collisions. If the filename is
`<project>-<ref>` or the ref is a sha, the sha will be omitted,
otherwise the default filename will be used.
- deprecate previous archive route `repository/<ref>/archive`

Remove superfluous lib: true, type: redis, service: true, models: true, services: true, no_db: true, api: true

==================
= Implementation =
==================

1. The path of the page is of the form 'group/project/pages/domains/<domain_name>'
2. Rails looks at `params[:id]` (which should be the domain name), and finds the
   relevant model record.
3. Given a domain like `foo.bar`, Rails sets `params[:id]` to `foo` (should be
   `foo.bar`), and sets `params[:format]` to `bar`
4. This commit fixes the issue by adding a route constraint, so that
   `params[:id]` is set to the entire `foo.bar` domain name.

=========
= Tests =
=========

1. Add controller specs for the `PagesDomainController`. These are
   slightly orthogonal to this bug fix (they don't fail when this bug is
   present), but should be present nonetheless.
2. Add routing specs that catch this bug (by asserting that the `id`
   param is passed as expected when it contains a domain name).
3. Modify the 'RESTful project resources' routing spec shared example to
   accomodate controllers where the controller path (such as
   `pages/domains`) is different from the controller name (such as
   `pages_domains`).

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

We need to do two things to support this:

1. Simplify the regex capture in the routing for the CommitsController
   to not exclude the '.atom' suffix. That's a perfectly valid git
   branch name, so we shouldn't blow up if we get it.
2. Because Rails now can't automatically detect the request format, add
   some code to do so in `ExtractPath` when there is no path. This means
   that, given branches 'foo' and 'foo.atom', the Atom feed for the
   former is unroutable. To fix this: don't do that! Give the branches
   different names!

This is the git default and will help to prevent false positive matches.

Closes #12706

Using the fuzzy filter, develop "file finder" feature.
- feedback(http://feedback.gitlab.com/forums/176466-general/suggestions/4987909-add-file-finder-fuzzy-input-in-files-tab-to-ju )
- fuzzy filter(https://github.com/jeancroy/fuzzaldrin-plus)
- shortcuts(when "t" was hitted at tree view, go to 'file find' page and 'esc' is to go back)
- depends on gitlab_git 7.2.22
