Summary: Ref T12270. This just drops the constraint for now, rather than dealing with all the typecasting stuff and putting us in a position which will almost certainly require backward compatibility breaks in the future. Also renames "badges.*" to "badge.*" for consistency (all other methods are singular: token.*, project.*, differential.revision.*, etc). Test Plan: Saw "qualities" now "Not Supported", while other constraints continue to work: {F3887194} Reviewers: chad Reviewed By: chad Maniphest Tasks: T12270 Differential Revision: https://secure.phabricator.com/D17487
