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.
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.
Closesgitlab-org/gitlab-ce#37534.
