Most changes are not very interesting to sleuth, though the server is
quite a lot better with UI fixes galore. For sleuth mainly, small api
unaffecting glitch fixes around the Span.Builder.
Here are the features relevant to sleuth
* MySQL support of 128-bit group-by
* don't stack overflow on json write bug
* more forgiving of IPv4-mapped addresses in json
Now that Endpoint has ipv6, the factory method is even worse than it
was before. This switches to a builder instead.
Note: Endpoint now has a nice toString which should help debugging.
AsyncReporter is a more robust version of what we were doing before.
Notably, it can give a memory threshold instead of span count for the
backlog. This change ports to use AsyncReporter internally.

TraceFilter no longer is a OncePerRequestFilter
TraceFilter processes the request that is executed upon ERROR dispatch (the logs will be present there)
Altered the logic in TraceFilter that an already processed request will not be detached (which resulted in an exception)
Added some debugging to instrumentation
Added assertion over a list of spans
Bumped up SC-Netflix to 1.1.2.BUILD-SNAPSHOT
Added Zuul integration tests
Added Http keys injection to Zuul client call
Zipkin 1.1.1 includes a few changes relevant to sleuth:
* Adds JSON button to trace detail screen
* Presents server errors in UI
* Fixes misclassification of http span metrics (1.1.1)
https://github.com/openzipkin/zipkin-java/releases/tag/1.1.0
This moves to changes made in preparation of zipkin 1.0.
Here are the notables:
* Zipkin has autoconfiguration modules, where maven artifacts have the prefix 'zipkin-autoconfigure-X'
* Zipkin's ui now shares a version with everything else
* Zipkin now namespaces packages and configuration. ex zipkin.storage.X as opposed to zipkin.X
* All autoconfiguration classes are prefixed `Zipkin` to be easier to find
* Zipkin binds components like StorageComponent, as opposed to individual classes like SpanStore.
* Health checks are under the scope "zipkin" and broken down by component
* UI responsiveness is better by conditionally caching names queries for 5 minutes
* New `Collector` class, which makes logging and metrics patterns the same regardless of transport
