This update fixes the following bug among others:

• Previously, the Prometheus swagger definition contained a $ref property which could not be resolved. This caused a runtime error to occur when using the Prometheus operand creation form. This was fixed by adding a definitions property to schema returned by the definitionFor helper function so that the $ref property can resolve. There are no longer runtime errors when using the Prometheus operand creation form. (BZ#1885228)
