Change status text by setting?

[mathomp4]

After you fixed my issue #26, we are now testing out using required labels in our system. Huzzah!

But now I have a question for the devels. Would it be possible to have the status text on github, which I controlled by, I think:

required-labels/utils.py

Lines 46 to 51 in 0fddb9c

	def create_status_json(self, required_any, required_all, banned):
	passes_label_requirements = self.validate_labels(required_any, required_all, banned)
	if passes_label_requirements:
	description = "Label requirements satisfied."
	else:
	description = "Label requirements not satisfied."

be dynamic and changeable in the Heroku settings? It would be nice if the check returns a failure that it could say:

Label requirements not satisfied: You must add at least one of label1, label2, label3

where the label1, etc. are the required-any labels (or whatever) we've decided to be required.

Now, I'm going to add a PR template explaining this so they know they need a label, but as is well known, if a template has comments, they can be easily ignored.
