Bump to 0.8.0

This release inaugurates the work of making cernan an at-once delivery
kind of system. This is John K's main show. We've also included the
feedback of end-users into the prometheus sink, making it behave more
like what folks expect and not breaking the bank in doing so:

  * da543d3 :: Introducing chan-signal & Signal Handling (#333)
  * c038a77 :: Remove any unwrap / excepts in prometheus critical path (#338)
  * 9b274cb :: Dramatically improve prometheus write speed, report CPU
  * 428bf5b :: Allow end-users to configure statsd error bounds (#341)
  * c5aaad4 :: Allow an 'enabled' flag to be set for firehose sink (#342)
  * c084e60 :: Windowing for prometheus sink's Summaries (#344)
