Log the following information in email headers: * X-Danbooru-User: the user's name and ID. * X-Danbooru-IP: the user's IP. * X-Danbooru-Session: the users' session ID. * X-Danbooru-URL: the page that triggered the email. * X-Danbooru-Job-Id: the ID of the background job that sent the email. * X-Danbooru-Enqueued-At: when the email was queued as a background job. * X-Danbooru-Dmail: for Dmail notifications, the link to the Dmail. * X-Request-Id: the request ID of the HTTP request that triggered the email. Also make it so we log an event in the APM when we send an email.
