without this change when dealing with Zuul, it's TraceFilter that is closing a span on an error
with this change, we're allowing the PostZuulFilter to close that span and TraceFilter doesn't interfere
fixes#563
without this change when an executor implementation was a final class or had a final method - the application wouldn't start or would produce NPE at startup.
with this change we have a custom bean post processor that wraps an aspect manualy either via a JDK Proxy when a class is final or a method is final or creates a CGLIB proxy if that's possible.
fixes#550
without this change when user adds a callback then it's not wrapped in a trace representation, thus when executed in a separate thread, it's then missing all the tracing information
with this change we're wrapping the future in our representation that passes the tracing information around
fixes#546
without this change we get exceptions related to not being able to extend a final class
with this change we're not wrapping any final types and we have a custom bean post processor for okhttp
fixes#513
without this change when someone has a missing ErrorController bean then TraceHandlerInterceptor blows up
with this change that problem gets fixed
fixes#512
without this change there's a problem with the time when the SS is set on a span. Currently it's done in TraceFilter's finally block. The problem is that this code is executed after the response has been sent back to the client. Thus CR sometimes was set faster than SS (it doesn't make any sense from the logical point of view).
with this change we're introducing wrappers over the HttpServletResponse where we annotate the span with SS just after the response gets sent to the recipient.

fixes#492#431
without this change you couldn't register your own client (for example to set your ssl config) for Sleuth to reuse it
with this change we're reusing a registered feign client bean or creating a default one if necessary
fixes#502
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.
Local Ip determined from spring.commons InetUtils.
To enable local endpoint resolution via service discovery, DiscoveryClient must be present and 'spring.zipkin.service.locator.discovery' should be set to true.
FallbackHavingEndpointLocator was caching and recreating EndpointLocator in the same time - removed the caching part.
Fixes gh-403
