v0.8.0

What's Changed

• Add an optional, pluggable RecoveryStrategy for half-open probing, by @ahinkle in #19. Implement the contract and set recovery_strategy on a service to control how a recovered service is tested (for example, warming a slow service back up gradually instead of returning to full speed on the first success). It resolves through the container, just like failure_classifier.

The default SingleProbe strategy preserves existing behavior exactly, so no configuration is needed and there are no breaking changes.
