Open ticket with button or command

[dlsnyder8]

Taken from Suggestion #438 in Discord

Please describe the feature you'd like Allow users to open ModMails using a button like so:

Perhaps we could only add this in a channel with setup if that makes it easier to implement.

Also add a command that can be used in a server to create a ticket for that server.

Implement with Slash commands so that messages can be ephemeral and secret to avoid sharing details w/ other server members.

TODO After d.py2.1+ update

Additional context Approved by Chamburr, making issue for tracking purposes

Is there a specific library that you want to use with this? Or whatever works?

[chamburr]

Whatever that works is fine yeah
