A few years ago we set the default number of retries to 3 globally. The
reasoning was that we have a lot of jobs that try to communicate with
external services, and that those jobs don't need 25 retries - if the
service is down, we shouldn't waste our time trying to send to it the
other 22 times.

I think that this is valid, but it has some problems as a default:

1. Most of our workers don't connect to an external service.
2. 3 retries will happen over a couple of minutes. If - say - our
   database goes down for 5 minutes, all jobs that we tried during that
   period will fail completely. If we allow 25 retries then we have a
   few weeks to fix that issue, which should be sufficient.
3. We're rolling out a change to use fewer Sidekiq queues. Because we
   have a mixed-stage deployment, we can have jobs scheduled from canary
   using new worker classes that don't exist on the main stage (which
   runs Sidekiq) yet. Those jobs would just fail immediately. Setting a
   higher number of retries lets those jobs succeed once the main stage
   is deployed - albeit with a delay due to the back-off.

The meta-reasoning here is that 25 is the default in Sidekiq for a
reason, and in retrospect I think we were too hasty in changing it.
Sidekiq is very heavily used software, and its default settings have
come out of a lot of hard-won experience. Let's try to use more of that!

Some time ago, we set the default number of Sidekiq retries to 3. In the
next commit we're going to change that to 25, but we only want it to
apply to new workers. So we'll first need to explicitly set all existing
workers to 3.

To aid with this, I used the below script. I had to make a couple of
tweaks for some worker concerns, but it covered most of the several
hundred workers we have:

    Dir.glob('{ee/,}app/workers/**/*.rb').select do |worker|
      contents = open(worker).read

      next unless contents.include?('ApplicationWorker')
      next if contents.include?('sidekiq_options retry: ')

      new_contents =
        contents.gsub(/^( +)include ApplicationWorker$/,
                      "\\1include ApplicationWorker\n\n" +
                      "\\1sidekiq_options retry: 3")

      open(worker, 'w').puts(new_contents)
    end
