This allows course authors to choose between two difference licenses for their course content: All Rights Reserved, or Creative Commons. In the backend, XBlocks that wish to allow custom licenses need only inherit from LicenseMixin, which adds a `license` field as a string. License information is displayed in the Studio editor view, and just below the rendered XBlock in the LMS. In addition, if the course block itself has a custom license set, this license will display just below the main body of the page on courseware pages. This entire feature is gated behind the LICENSING feature flag.
