  Originally, this method factored in the effect of requests going to the server as well. However, this does not interact very well with the current region rebalancing code, which only factors number of regions. For the interim, until we can figure out how to make rebalancing use all the info available, we're just going to make load purely the number of regions.
  
  Returns:
  load factor for this server
