Simplify trace_context tests (#2108)
* Simplify trace_context tests

Refactor the propagation/trace_context tests to be targeted at testing
the propagator functionality only and remove extraneous dependencies.

Fix the TraceContext Inject method from injecting the tracestate header
if no value exists.

Store current Span instead of local and remote SpanContext in context.Context (#1731)
* Store Span instead of local/remote SpanContext in Context

Now that the SpanContext has a remote identifier, storing a Span's
SpanContext two separate ways in a Context (one for local another for
remote) is unnecessary and adds complication throughout the project when
determining heredity of a Span. This moves to storing the Span directly
in the Context uniformly (for both local and remote) as current Span. In
the process, it updates the getter/setter functionality the `trace`
package provides and replaces the distributed heredity logic throughout
the project with just using the current Span as the parent if it exists.

Update the TraceContext.Extract docs (#1720)
How the tracecontext is extracted is important if the user wants to
interact with the extracted SpanContext (i.e. as a remote span context
instead of a current span context). This makes it clear where it will be
extracted and what behavior to expect if the tracecontext is invalid.

d351eb4de2 Http interceptors (#156)
* WIP

* Finish http middleware implementation

This is currently done as httptrace.NewHandler(). This should maybe
be moved to a different package or renamed, but atm this name
seemed the least objectionable to me.

There are a few TODOs sprinkled in the code for questions I didn't
know the answers to.

There is an example provided, which when copied to a main func
locally work against the jaeger all in one.

Real tests need to be added.

* Address feedback

* Tie in propagation, update attributes, more options, revise example, etc.

Dropped the httpConfig type because it seemed redundant an unecessary
abstraction.

* WithRouteTag

* address out of band feedback

* move to othttp package

* Add a very basic test.

I ended up needing to export the Traceparentheader const so that
it was accessible to this test.

* Add file header
