Enables frozen string for some vestigial files as
well as the following:

* app/controllers/projects/**/*.rb
* app/controllers/sherlock/**/*.rb
* app/controllers/snippets/**/*.rb
* app/controllers/users/**/*.rb

Partially addresses #47424.

This whitelists all existing offenses for the various CodeReuse cops, of
which most are triggered by the CodeReuse/ActiveRecord cop.

git-lfs 2.5.0 now sets the Content-Type header instead of hard-coding it to
application/octet-stream: https://github.com/git-lfs/git-lfs/pull/3137

To avoid this issue, we explicitly tell the client to use
application/octet-stream.

Closes #49752

This makes accessing LFS Objects for a project easier

  project.lfs_storage_project.lfs_objects`

becomes

  project.all_lfs_objects

This will make the refactor in
https://gitlab.com/gitlab-org/gitlab-ce/issues/39769 easier to deal
with.

In GitLab EE, a GitLab instance can be read-only (e.g. when it's a Geo
secondary node). But in GitLab CE it also might be useful to have the
"read-only" idea around. So port it back to GitLab CE.

Also having the principle of read-only in GitLab CE would hopefully
lead to less errors introduced, doing write operations when there
aren't allowed for read-only calls.

Closes gitlab-org/gitlab-ce#37534.

Use the EnforcedStyleForMultiline: no_comma option.

LFS has the `authenticated` field in the response for downloads of
objects to indicate that the object does not need authentication to
access it.

Spec: https://github.com/git-lfs/git-lfs/blob/master/docs/api/batch.md#successful-responses

Fixes #23360.

Also create a new WorkhorseRequest concern

It is needed for the `lfs_check_access!` callback when the repository size limit is enabled (EE only).
