Requests over the rate limit are logged into `auth.log`

- move uploads created by AttachmentUploader
- handle also files created for legacy_diff_notes

The githost.log name was often confused with GitHost.io. Rename this to
git_json.log to make it clear it's coming from Git and that it's JSON
data.

A project can have the same `LfsObject` linked with up to three
`LfsObjectsProject` records. Each of these records would be for a
different repository, recorded in the `repository_type` property. The
different repositories at time of writing are "project", "wiki", and
"design". See https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/13894

This change exports the list of `repository_type`s as a JSON mapping of
oid => repository_types, which are imported to recreate the correct
`LfsObjectsProject` records.

This will make it easier to parse this in production and adds the
`correlation_id` if available.

Change assorted absolute links to ce and ee docs
to relative links

From 12.1, user information (id and username) are also included on
auth.log. Documentation was updated to reflect this.

Creates a new filename to register auth logs.
This change should allow SRE's queries to make better queries
through logging infrastructure.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/54528

This makes it easier to debug Gitaly performance issues in the field.

This commit also makes the tracking of query time thread-safe via
RequestStore.

`queue_duration` is a useful metric that is currently in api_json.log
but not in production_json.log. We should add it because it tells us how
long the request sat in Workhorse before Unicorn processed it. Having
this field enables the support team to better troubleshoot when delays
began to happen.

This will add audit_json.log that writes one line per audit event. For
example:

{
       "severity":"INFO",
       "time":"2018-10-17T17:38:22.523Z",
       "author_id":3,
       "entity_id":2,
       "entity_type":"Project",
       "change":"visibility",
       "from":"Private",
       "to":"Public",
       "author_name":"John Doe4",
       "target_id":2,
       "target_type":"Project",
       "target_details":"namespace2/project2"
}

Adds an importer.log so that it's easier to track what's happening with the import.

Closes #20060

The Sidekiq exporter logs were mixing with the normal Sidekiq logs. In order
to support structured logging in Sidekiq, we either need to split this data
out or convert the exporter to produce structured logs. Since Sidekiq job
processing is fundamentally different information from Web server traffic,
it seems cleaner to move the metrics traffic into a separate file, where they
can be parsed by a different filter if needed.

No matter which environment Gitlab was running as, the admin/logs view
always showed production.log. This commit selects the logfile based
on Rails.env.
