This deprecates span transports in favor of `spring-cloud-sleuth-zipkin2`
which:
* Supports RabbitMQ and Kafka automatically when adding spring-rabbit or spring-kafka deps
* Supports any io.zipkin.reporter2:zipkin-reporter sender, including Amazon X-Ray
* Defaults to zipkin v2 format, but can be configured to use zipkin v1 format as needed
This lowers the amount of maintenance on the project, as discussed in various issues
See #727
See #711
without this change you have to add a `@Primary` annotation around your custom `TraceFilter` bean to alter the behaviour of the current `TraceFilter` implementation
with this change we're marking the `TraceFilter` as conditional on missing bean; also we're ensuring that the registered `SkipPatternProvider` will be reused when no explicit pattern was set.
also documentation is added
fixes#633
without this change there's no way to alter the name of the methods annotated with @Async
with this change the value passed to @Async annotated method via @SpanName will be the name of the span
fixes#653
The main arguments for these features are
* api-agnostic means to collaborate with a span
- use of annotations allows users to add to a span with no library dependency on a span api.
This allows Sleuth to change its core api less impact to user code.
* reduced surface area for basic span operations.
- without this feature one has to use the span api, which has lifecycle commands that
could be used incorrectly. By only exposing scope, tag and log functionality, users can
collaborate without accidentally breaking span lifecycle.
* collaboration with runtime generated code
- with libraries such as Spring Data / Feign the implementations of interfaces are generated
at runtime thus span wrapping of objects was tedious. Now you can provide annotations
over interfaces and arguments of those interfaces

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

without this change it's pretty much impossible to enforce sampling for certain traces
with this change setting the X-B3-Flags to 1 for HTTP messages / spanFlags to 1 for messaging will override any sampling decisions

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

without this only either service discovery service id / spring.application.name can be chosen as a service name for zipkin
with this change you can pass spring.zipkin.service.name property to change override that both for HTTP and Stream collectors
