Restart additional services when ruby is updated

Fixes #4300 (closed)

• In the rails recipe, ensure sidekiq,sidekiq-cluster, unicorn, workhorse, mailroom and puma get restarted if the ruby version changes
• In the gitlab-monitor recipe, ensure gitlab-monitor is restarted if the ruby version changes. (Added here as there is no guarantee that the gitlab-rails recipe will be enabled on the same node as gitlab-monitor)
