disable markdown in comments when referencing disabled features

fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/23548

This MR prevents the following references when tool is disabled:

- issues
- snippets
- commits - when repo is disabled
- commit range - when repo is disabled
- milestones

This MR does not prevent references to repository files, since they are just markdown links and don't leak
information.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/22481

Bring back the old JIRA docs

## What does this MR do?

Bring back the old JIRA docs

## Why was this MR needed?

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6598 introduced new
JIRA settings, but that's not yet released. Since our documentation is currently
built using the master branch, users are having issues where the docs show
different settings than what GitLab's latest stable release supports.

Improved build page scroll UX

## What does this MR do?

This MR smoothes the UX of the builds page by more effectively affixing the scroll step buttons.

It also ensures the scroll step buttons are always in view, even if the sidemenu is open.

It also moves the autoscroll button into the same container as the scroll buttons.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

The build scroll buttons are always in unpredictable places and are often hidden behind sidemenus.

Replace jQuery.timeago with timeago.js

## What does this MR do?
Replaces jQuery.timeago with [timeago.js](https://github.com/hustcc/timeago.js)

## Are there points in the code the reviewer needs to double check?

*  Check to make sure its working everywhere 😄 
*  Check to make sure the timeago wording matches what we have now (I think I've got this down but an extra pair of 👀 would help too)

*  timeago.js is smaller (7.19 KB => 4.52 KB)
* timeago.js has no jQuery dependency
* removes all inline javascript ⚔  for timeago

As noted in gitlab-com/support-forum#1270, omniauth-gitlab fails if omniauth-oauth2 is bumped to 1.4.0, OAuth2 quietly fails due to https://github.com/linchus/omniauth-gitlab/issues/10:

```

```

This was fixed and discussed here:
