[API] Omit `X-Total` and `X-Total-Pages` headers when items count is more than 10,000

Closes #42194 and #52674

See merge request gitlab-org/gitlab-ce!23931

Prior to GitLab 9.0, attachments were not tracked the `uploads` table,
so it was possible that the appearance logos were just stored in the
database as a string and mounted via CarrierWave.

https://gitlab.com/gitlab-org/gitlab-ce/issues/29240 implemented in
GitLab 10.3 was supposed to cover populating the `uploads` table for all
attachments, including all the logos from appearances. However, it's
possible that didn't work for logos or the `uploads` entry was orphaned.

GitLab instances that had a customized logo with no associated `uploads`
entry would see Error 500s. The only way to fix this is to delete the
`logo` column from the `appearances` table and re-upload the attachment.

This change makes things more robust by falling back to the original
behavior if the upload is not available.

This is a CE backport of
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/9277.

documentation: Add `git clone` to list of basic git commands

Closes #56514

See merge request gitlab-org/gitlab-ce!24474

This started with
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24339 where a
broken link was introduced, but the lint checker never caught it.

The docs-lint job does the following:

```yaml
  script:
    - mv doc/ /tmp/gitlab-docs/content/
    - cd /tmp/gitlab-docs
    # Build HTML from Markdown
    - bundle exec nanoc
    # Check the internal links
    - bundle exec nanoc check internal_links
```

It moves the `doc/` dir inside `content` where Nanoc is expecting the
markdown files to be. It then builds the site and finally checks for
the links. If the built website was deployed to production, that would
be under `docs.gitlab.com/doc`.

The interesting part here is that
`[the logs](/doc/administration/logs.md#productionlog)`
translates to `<a href="/doc/administration/logs.html#productionlog>`,
so, Nanoc correctly sees this as an existing file!

This MR changes the path of the docs content to be equal to
$DOCS_GITLAB_REPO_SUFFIX which is defined as an environment
variable and takes the value of the slug of each project:
'ce', 'ee', 'omnibus', 'runner'.
