- To hold registrations from U2F devices, and to authenticate them.
- Previously, `User#two_factor_enabled` was aliased to the
`otp_required_for_login` column on `users`.
- This commit changes things a bit:
- `User#two_factor_enabled` is not a method anymore
- `User#two_factor_enabled?` checks both the
`otp_required_for_login` column, as well as `U2fRegistration`s
- Change all instances of `User#two_factor_enabled` to
`User#two_factor_enabled?`
- Add the `u2f` gem, and implement registration/authentication at the
model level.

Colorize is a gem licensed under the GPLv2, so we can’t use it in GitLab without relicensing GitLab under the terms of the GPL. Rainbow is licensed under the MIT license and does the exact same thing as Colorize, so Rainbow was added in place of Colorize.
The syntax is slightly different for Rainbow vs. Colorize, and was updated in accordance.
The gem is still a dependency of Spinach, so it’s included in the development/test environments, but won’t be packaged with the actual product, and therefore doesn’t require we relicense the product.
An attempt at relicensing Colorize was made, but didn’t succeed as the library owner never responded.

Resolve "SHA parameter in accept merge request API"
Add a `sha` parameter to the MR merge API, which must match the source SHA for the branch to be merged.
Also add the same parameter to the UI:

@DouweM and I discussed adding some smart feature to that, like updating the source SHA on navigating to the diff tab, but for now it will just require a refresh 😃Closes#14139.

This changes UserReferenceFilter so it operates using the following
steps:
1. Grab all username references from the input document.
2. Query the corresponding Namespace objects using a single query.
3. Iterate over all nodes to build links while re-using the objects
queried in step 2.
The impact of these changes is that a comment mentioning 5 different
usernames no longer runs 5 different queries (1 for every username),
instead it only runs a single query.
This method returns an Array of the HTML nodes as yielded by
ReferenceFilter#each_node. The method's return value is memoized to
allow multiple calls without having to re-query the input document.
Nokogiri's `node.replace` was being unnecessarily called for every text node in
the document due to a comparison bug. The code previously was comparing the
HTML representation of the full document against the text node, which would
always fail. Fix the comparison to just compare the modified text.
Closes#18011
The `sha` parameter is optional, and when present, must match the
current HEAD SHA of the source branch. Otherwise, the API call fails
with a 409 Conflict and a message containing the current HEAD for the
source branch.
Also tidy up some doc wording.
Separate reference gathering from rendering
This is a required step to allow batch processing when gathering references. This in turn would allow grabbing (for example) all mentioned users of an issue/merge request using a single query.

Fix 404 page when viewing TODOs that contain milestones or labels in different projects
A user viewing the TODOs page will see a 404 if there are mentioned milestones or labels in multiple different projects. This is likely a caching bug and only occurs
when Markdown rendering occurs across multiple projects, which is why it's so tricky to reproduce. This is what I think is happening:
1. LabelReferenceFilter#references_in encounters label ~X for ProjectA and finds the label in the DB as id = 1.
2. LabelReferenceFilter.references_in yields [1, 'X', nil, ...]
3. Since project_ref is nil, AbstractReferenceFilter#project_from_ref_cache caches nil => ProjectA.
4. LabelReferenceFilter#references_in encounters label ~Y for ProjectB and finds the label in the DB as id = 2.
5. LabelReferenceFilter.references_in yields [2, 'Y', nil, ...]
6. AbstractReferenceFilter#project_from_ref_cache lookups nil and returns ProjectA. It was supposed to be ProjectB.
7. A is the wrong project, so the label lookup fails.
This MR expands the `project_ref` to the right value as soon as we have it to avoid this caching bug.

This fixes an issue where the RequestStore was being populated with the settings in the unicorn master
during the rails initializers. Each forked worker would then start their first request with an uncleaned RequestStore.
This splits the Markdown rendering and reference extraction phases into
two distinct code bases. The reference extraction phase no longer relies
on the html-pipeline Gem (and any related code) and allows for
extracting of references from multiple HTML nodes in a single pass. This
means that if you want to extract user references from 200 comments you
no longer need to run 200 times N number of queries, instead only a
handful of queries may be needed.
