Fixes deployment id to show the internal one

Skipped jobs should be considered successful

## What does this MR do?

If all jobs in previous stage are all skipped, the next stage should consider previous stage succeeded.

## Why was this MR needed?

Since for now we consider all manual jobs if skipped, should not block the next stage from running.

Closes #22598

Fix small typo in using_docker_images.md, file is called `build_script` (using underscore)

## What does this MR do?

This MR fixes a very small typo in the using_docker_images.md documentation, a space was used in the filename `build_script` while it should be an underscore. Not sure of a MR is the best way to get this changed, trying it anyway :).

## Moving docs to a new location?

No

Remove lease from Event#reset_project_activity

## What does this MR do?

This removes the exclusive lease used by `Event#reset_project_activity` in favour of conditional UPDATE queries. See dbcc623a901cb3fb725976217416bafad73dbf69 for more information.

## Why was this MR needed?

Obtaining the lease can, for whatever reason, be _really_ slow. See https://gitlab.com/gitlab-org/gitlab-ce/issues/22473 for more information.

Fix project deletion when feature visibility is set to private

Projects that are destroyed are put in the pending_delete state.
The ProjectDestroyWorker checks whether the current user has
access, but since the ProjectFeature class uses the default scope
of the Project, it will not be able to find the right project.

This was a regression in 8.12 that caused the following stack trace:

```

Per GitLab.com's performance metrics this method could take up to 5
seconds of wall time to complete, while only taking 1-2 milliseconds of
CPU time. Removing the Redis lease in favour of conditional updates
allows us to work around this.

A slight drawback is that this allows for multiple threads/processes to
try and update the same row. However, only a single thread/process will
ever win since the UPDATE query uses a WHERE condition to only update
rows that were not updated in the last hour.

Skip wiki creation when GitHub project has wiki enabled

## What does this MR do?

When importing a repository from if the repository has wiki, we should not create the default wiki. Otherwise the GitHub importer will fail because the wiki repository already exist. This bug was introduced here https://gitlab.com/gitlab-org/gitlab-ce/commit/892dea67717c0efbd6a28f7639f34535ec0a8747

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

No.

## Why was this MR needed?

Adds v-pre to code blocks in comments

## What does this MR do?

Allows users to comment on discussions with code that contains `{{`

Previously because of the discussion part being a Vue app it was being converted by Vue & therefore creating JS errors & the code not displaying correctly. This adds `v-pre` onto the code element to allow the user to write code that would contain `{{`

Restrict failed login attempts from users with 2FA enabled.

See merge request !6668

Copy logic from `Devise::Models::Lockable#valid_for_authentication?`, as
our custom login flow with two pages doesn't call this method. This will
increment the failed login counter, and lock the user's account once
they exceed the number of failed attempts.

Also ensure that users who are locked can't continue to submit 2FA
codes.

Closes #22911

Ensure the 'fixed layout' preference is honored whenever possible

## What does this MR do?

Currently, when viewing any Merge Request the user's fixed-layout preference is overridden if they have set "Side-by-Side" view as their preference when viewing diffs.  This makes sense if they are currently viewing a diff, but this is confusing when their layout preference is overridden while they are on another tab (i.e. "Discussion" or "Builds").

This MR moves all responsibility for overriding the fixed layout from the Ruby page layout helper into frontend JavaScript where it is only applied when needed.

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

Check that nothing broke for users which have their layout preference set to "Fluid" as well as those which have it set to "Fixed".  I've already done this but double checking is always good idea 😄.

## Screenshots (if relevant)

Closes #22343 

## Other Notes

As @lbennett noted in #22343, this is something of a band-aid.  It fixed most of the issue, but we still need to have a discussion about whether or not is acceptable to override user layout preferences for "Side-by-Side" views in general.  At least this MR limits the scope of this behavior to a single tab within an MR or merge conflict page.

Upgrade acts-as-taggable-on from 3.5.0 to 4.0.0.

## What does this MR do?

Changelog: https://github.com/mbleigh/acts-as-taggable-on/blob/master/CHANGELOG.md#400--2016-08-08

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

That this works without the migrations, I don't believe the upgrade from 3.5.0 to 4.0.0 requires any migrations since [UPGRADING.md hasn't been updated since 3.5.0 was released](https://github.com/mbleigh/acts-as-taggable-on/blob/master/UPGRADING.md). It's kind of unclear, unfortunately.

## What are the relevant issue numbers?

Fixes #22082. Working toward Rails 5: #14286.

## Why was this MR needed?

The issue template shouldn't override the issue content without warning.

We remove some arguments that are rarely used or 
used just to simplify setups on specs.

Modified Mentionable#create_new_cross_references method 
we don’t need to calculate previous references to avoid the 
duplication because we do that at database level when 
creating references extracted from the current entity state.

MergeRequests won’t create cross_references for commits that are included so we change a spec to use a different merge request to make references to commits to other branches
