Currently, the angular "bytes" filter in horizon/static/horizon/js/angular/filters/filters.spec.js will report up to TeraBytes, but not up to PetaBytes. The equivalent python code does, so we've lost some feature parity.

Also, the method can/should accept a specific unit, and output everything in that unit as opposed to reducing to the largest plausible unit.
