GL dropdowns in issuable form ## What does this MR do? Changed all the issuable dropdown menus over to user GL dropdowns. This brings the dropdowns to be inline with the issuable filter dropdowns and allows for labels to be created whilst creating/editing an issuable. ## What are the relevant issue numbers? Closes #12574 ## Screenshots (if relevant) See merge request !4970
Make "Get started with Builds" Help Page link work properly
`help_page_path('ci/quick_start', 'README')` causes a link to `https://gitlab.com/help/ci%2Fquick_start/README` which in turn breaks every relative link on the page. This remedies the problem.
That said, this is probably a horrible way of fixing this issue, *but* it does work. I can’t find much information on linking this deeply with Rails routes.
If anyone has suggestions as to a better way of handling this, I'll gladly take them. I tried a few different things, but none of them really worked.
Resolves #14872.

Single file diffs Closes #14103. Related (not part of this MR): #19553. This adds a `diff_for_path` action to each place we render diffs (commit, compare, new MR, existing MR) which renders the diff for a single path. The action is always available with the same params as the 'parent' action, to make it simpler to generate the URIs. If a diff is bigger than 10 KB, it will be collapsed by default and have a data attribute added. You can then click the message or the filename to expand that diff. For expanded files, you can collapse and expand them, but they won't make any AJAX requests.  See merge request !4990
Use Gitlab-Workhorse-Send-Data to send entry ## What does this MR do? Use Gitlab-Workhorse-Send-Data to send entry: Closes #19224, Closes #19128 Also requires this MR to work: https://gitlab.com/gitlab-org/gitlab-workhorse/merge_requests/53 ## Are there points in the code the reviewer needs to double check? Do we have a test for this? ## Why was this MR needed? This way gitlab-workhorse does not have to call any API. See merge request !5094

With the option to expand and collapse individual diffs, these aren't needed any more.
