Zipkin 1.0

Many of you noticed we've been working on a new dependency-light codebase for Zipkin.

Over the last 10 months we've gone beyond feature parity with the previous server, and reduced moving parts until zipkin could be deployable as a single process. The new codebase also includes new features like Elasticsearch and better metrics.

Those already using zipkin should know zipkin-java is schema, api, and environment variable compatible with the old servers. We took great care to ensure it is a drop-in.

Those worried about being first to the fire will be interested in the fact that this code has been in development for 10 months and used in production already by companies like Bouyant, LINE.me and anyone using Spring Cloud Sleuth.
