Force people to enter a "reason" when requesting access to a group

[sam (Sam Saffron)]

I am noticing at least 3 times a week people are asking for access to the #plugin group when in fact they are either spam bots or people clicking the join button by mistake.

We should force people to enter a “reason” when they ask for access, and ideally allow a “custom” justify why you belong in the group message.

For example for plugin authors I would have the prompt be:

Please include a link to your plugin in the box below. eg: https://github.com/bob/my_awesome_plugin

This would save me a bunch of regular work and I am sure would save work for others

@tgxworld can you make this change?

After the request is submitted, could also change the button from

Request to Join Group

to

Cancel Request

The modal will look something like

“custom” justify why you belong in the group message.

This is exposed as a membership_request_template instead just like how we do it for category topic template.
