Title:
  swift-ring-builder rebalance goes into an infinite loop

Status in swift package in Ubuntu:
  Confirmed

Bug description:
  On Ubuntu 16.04 with a Mitaka cloud the attached ring files cause
  swift-ring-builder to go into an infinite loop when asked to
  rebalance.

  The problem seems to be the following line in place_parts():

              while parts:

  Which seems to assume that parts can never be << 0, but with these
  ring files that assumption breaks.

  I added the following debug statements:
