Camel OpenTracing support
Initial version of the OpenTracing support - I used the zipkin component as
a template.
Originally the `OpenTracingTracer` was a `StaticService` (as in the
`ZipkinTracer`) but found when running the unit test which loads the route from
xml, it didn't cause the service to be started (`doStart()`) so the event
notifier was not registered. If it is preferred to have this class as a static
service, then I will update the PR and we can explore solutions.
To enable different components to record additional tags/logs in the span
data, I've created a `SpanDecorator`. Added decorators for http and jetty
currently - for some reason the service2 (in the example) http.status field is
not captured because Exchange.hasOut() returns false - and if getOut() is
accessed (without checking `hasOut()`), it results in no result being returned
from the service.
Not sure if other component decorators should be created in this component,
or whether they should be created in their own component modules - but then
they would have a dependency on the OpenTracing artifact.
