GKE network and subnetwork dropdowns

This MR implements two dropdown fields used by the GKE cluster configuration form: network and subnetwork. This MR only contains the dropdown component implementations but it does not integrate the dropdowns in the form. The purpose is to keep the size of the MR manageable. 

To test the dropdowns, please use the following integration MR https://gitlab.com/gitlab-org/gitlab/merge_requests/22344

Frontend - Resolve "Display in MR if security report is outdated"

See merge request gitlab-org/gitlab!20954

When the last pipeline for the target branch hadn't detected some
security issues, maybe due to jobs failed or artifacts expired, the
MR security report should be considered outdated and the pipeline needs
to be re-run. It also handles the edge case when target branch has
received more commits and the current branch needs to be updated.

Update Mermaid to v8.4.5

Resolve "Allow admins to disable users ability to change profile name"

See merge request gitlab-org/gitlab!21987

This fixes a problem rendering multiple graphs on the same page
(https://github.com/mermaid-js/mermaid/pull/1190).

Full list of changes: https://github.com/mermaid-js/mermaid/releases

Mermaid v8.4.4 also fixes an HTML escaping issue
(https://github.com/mermaid-js/mermaid/issues/903). Since HTML labels
are disabled, the HTML content can remain as-is, and we just need to
ensure the XSS doesn't actually get run.

Closes https://gitlab.com/gitlab-org/gitlab/issues/195802

The route `/uploads/:namespace/:project/:secret/:filename` has been
around for a long time, but it duplicates the
`/:namespace/:project/uploads/:secret/:filename` route. We'll redirect
the former to the second, canonical version in preparation for removing
this route entirely later.

Previously if a user attempted to click on a link to an attachment for a
renamed project (e.g. https://gitlab-org/gitlab-ce/uploads/123.png),
Rails would redirect the user to an erroneous URL
(e.g. https://gitlab-org/gitlab-foss/uploads/123.png.png). Notice the
redirect URL contains a redundant extension.

It turns out Rails 5 parses the extension of a route as the format
(https://github.com/rails/rails/issues/28901#issuecomment-297747521),
and the URL generator appends the format to the redirected route.

To fix this, we need to disable the format path parameter and explicitly
set the format to `nil`. If we do not set the format to `nil`, the URL
generator will append a query string (e.g `?format=png`), which would
still work but not necessary.

Closes https://gitlab.com/gitlab-org/gitlab/issues/196232

The div wrapping gl-alert was causing the
<image> to be pushed down the page, thus
causing the overlay to appear "above" where it was
meant to be.

This pulls GLAlert out of the div that wraps
design-image and design-overlay so as to not
interfere with any positioning

Show READMEs with .txt extension

Closes #25343

See merge request gitlab-org/gitlab!21763

There are two categories of README files: markup and plain text. For some
reason, READMEs with .txt extension disappeared from the plain text category,
leaving there only READMEs without extension. This MR returns .txt READMEs into
the plain text category so that they are again recognized as README files and
rendered on a project page.

Add spec for adding a message to

This was failing becuase container_expiration_policy was not created for
projects sometimes.

Rather than rely on that mechanismm create container_expiration_policy
directly for this spec
