    Add CPUWeigher

By default, all in-tree weighers are loaded when scheduling, but also by default their weight multiplier makes them do nothing (no-op) and we already have weighers for ram and disk, so this seems fine. -- mriedem 20180315

There was agreement in today's nova meeting to approve this specless blueprint. -- mriedem 20180315
