closes #13585 fixes #9067 fixes #2386 ref #6226 ref #6219 fixes #745 This PR adds support to process incoming emails to perform actions. Currently I added handling of replies and unsubscribing from issues/pulls. In contrast to #13585 the IMAP IDLE command is used instead of polling which results (in my opinion 😉) in cleaner code. Procedure: - When sending an issue/pull reply email, a token is generated which is present in the Reply-To and References header. - IMAP IDLE waits until a new email arrives - The token tells which action should be performed A possible signature and/or reply gets stripped from the content. I added a new service to the drone pipeline to test the receiving of incoming mails. If we keep this in, we may test our outgoing emails too in future.
