New bot idea: slack roulette

[loganmeetsworld]

It would be nice to have a slash command that took a slack group (like @foo-engineers) and selected a random person from that group. This would be helpful for selecting folks to take notes/run a meeting and other tasks that could use the benefit of randomness!

Bonus: ignore people on vacation by looking at status/name for OOO.

I've looked at https://github.com/aws/aws-ops-wheel before for similar tasks. Might be worth forking, checking out libraries, or borrowing logic if the license allows :)
