[GitLab] Enabled issue/MR reply and issue/MR creation by email

[Carlos Soriano <csoriano gnome org>]

Hello all,

We have just set up (thanks to the foundation staff, Bartolomej and Andrea) a feature of GitLab that allows to comment on issues/MR by simply replying to the notification email. It also allows issue and MR creation by sending an email to a specific address.

Please read the documentation first, it has some security considerations: If the email used by you gets shared publicly anyone could create issues on your behalf:

• Documentation to reply by email.
• Documentation to create an issue by email.
• Documentation to create a merge request by email.

Hope it's useful for you all, give us feedback whether this is useful for you or not or if it doesn't work as expected.
