Send `Auto-Submitted: auto-generated` header within auto-generated emails

Sending the Auto-Submitted: auto-generated header should prevent systems auto-replying

https://tools.ietf.org/html/rfc3834

Would be good if it could be added for all auto-generated emails from GitLab

Added emails label

Hi @smcgivern Has there been a discussion about this proposal?

I did have a quick look into setting the correct headers, but I think I realised quickly that the mail is handled by a 3rd party gem that doesn't make this easy ...

If I'm wrong, and is simply a few headers needing added somewhere, I'll happily create the MR for this

@Stretch96 nope, no discussion! I think this should be possible with an interceptor - maybe you could try that? Thanks for offering!
