sidekiq-ent periodic tasks support

[kichik]

Cron monitoring has built-in support for sidekiq-cron and sidekiq-scheduler. It would be great if the built-in cron feature of Sidekiq was supported as well. It is limited to sidekiq-ent (the paid version), but I imagine it's still popular enough to consider being included.

In our sidekiq.rb we have:

Sidekiq.configure_server do |config|
  config.periodic do |mgr|
    mgr.register("* * * * *", "TestJob") # every minute
  end
end

It would be awesome if our sentry.rb could have:

Sentry.init do |config|
  config.enabled_patches += [:sidekiq_ent_cron]
end

That way we don't have to manually implement check-ins.
