Many common file systems have a limit of 255 bytes for file and
directory names, and while Git and GitLab both support paths exceeding
those limits, the presence of them makes it impossible for users on
those file systems to checkout a wiki repository locally.

To avoid this situation, we enforce these limits when editing pages
through the GitLab web interface and API:

- 245 bytes for page titles (reserving 10 bytes for the file extension)
- 255 bytes for directory names

Resolve "Web IDE does not work on some branch name"

See merge request gitlab-org/gitlab!24717

To make sure we link to WebIDE correctly, we escape the ref part
(the one containing the branch name). This allows branches to contain
"#" character without breaking WebIDE when getting there by clicking
the "WebIDE" buttons in product.

Sidekiq::Queue only counts currently enqueued jobs. For background
migrations, most jobs are instead scheduled and therefore in
Sidekiq::ScheduledSet. This is because if we enqueued them all, we'd
process them as fast as Sidekiq could pick them up, which could:

1. Block other jobs from processing.
2. Overwhelm the database.

We attempted to revert the rename of the `template` to `instance` column
in the `services` table in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/24857 and
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/24885, but for
some installations (e.g. staging), the `template` column had been
dropped already because post-deploy migrations had finished.

We never actually shipped this change to production, but for these
environments we need to re-add the `template` column back into the table
or project creation will fail.

Note we do not do a data migration (e.g. set the `template` column to
true for rows that have a NULL `project_id`) for two reasons:

1. We don't want to insert a template by accident.
2. This rename only finished on development/staging environments.

Note that this migration happens in a post-deploy migration to ensure
`20200211152410_remove_instance_from_services.rb` gets a chance
to undo the migration first.
