This commit contains back end changes necessary to load programs from the catalog in all contexts. The existing program munging utility is applied as late as possible to avoid conflating this work with changes to the front end; those will be made separately.

Catalog-based MicroMasters need to be displayed in the LMS. However, the LMS currently retrieves all program data from the soon-to-be-retired programs service. Consuming program data exclusively from the catalog service is out of the question right now; it's too complex to confidently pull off in a week. This is a functional middle ground introduced by ECOM-5460. Cleaning up this debt is tracked by ECOM-4418.

This work removes most references to XSeries from the LMS in an attempt to be more general. ECOM-5018.

The new URL pattern expects a program ID and allows a program name to be included, if desired. It will match paths like 'programs/123/' and 'programs/123/foo/', but not 'programs/123/foo/bar/'. The given ID is passed to the view, where it will be used to retrieve program data. Part of ECOM-4415.
