"gig" board support tools

[vcarl]

We added a #looking-for-group forum channel, which is getting some decent volume of posts to it. I think it would benefit us to collect some information about how people are using it and share out information about how to make use of it and what the expectations are.

We should add a features similar to what we have for #resume-review, where the bot posts an embed to each new post with some interaction buttons. The buttons should include a simple "I reached out" interaction, as well as a button for folks to follow-up and report how the interaction went. Clicking "I reached out" responds with an acknowledgement and asks them to follow up later, clicking "follow up" asks then to report back how it went with a set of multiple-choice options (options like "it went well and I'm contributing", "I couldn't find a way to contribute", "not for me", "person is soliciting paid work", "I think this is a scam"
