Reorganize propagation code (shrink PR 381) (#444)

Browse Source 
* Rename distributedcontext package to correlation

Correlation is the name we agreed upon.

* Move trace propagators to api/trace

The trace propagators tests had to be moved to a testtrace subpackage
to avoid import cycles between api/trace and internal/trace.

Needed to shut up golint about stutter in trace.TraceContext -
TraceContext is a name of a W3C spec, so this stutter is
expected. It's certainly still better than golint's suggestion of
having trace.Context.

* Rename api/propagators to api/propagation

This package will not contain any propagators in the long run, just
the interface definitions.
