1.1.0

Added

• Report metric geocodecsv.selected_errors.count, which breaks down
  particularly interesting errors by component and cause. We focus on
  reporting this information for remote APIs, currently including BigTable and
  Smarty. This is meant to supplement the existing
  geocodecsv.chunks_retried.total and geocodecsv.chunks_failed.total
  metrics, which already report generic error statistics, but which can't say
  what failed or why.
