0.1.0-RC

This release is the release candidate for 1.0. At this point we'll be feature-frozen for 1.0 and will be working only on bugfixes and testing improvements until after 1.0 is shipped.

CHANGELOG (many thanks to @justenwalker!):

• added support for tags if discovery backend supports it (ex. Consul) #59
• added support for etcd service discovery backend #61
• expanded network interface specification syntax in the configuration #58
• fixed example application so that local runs will scale (thanks @dobbs!) #56
• some general build/CI cleanup
