Create webform for people to submit when they want us to grant them extension permission

Someone getting in touch and asking if they can publish an extension is a great milestone on our ladder of enagement. I'm thinking that if we could channel this through a webform, and have the email CCed to the right people who can both grant the permission and encourage them to get more involved, we would be able to capture the information in CiviCRM and use is an opportunity to deepen engagement with the person.

It would also streamline the process since we'll be able to click on their username and assign them the permission.

We should include suggested ways to engage the extension person in the email that goes out to the people who are going to give them permission.
