W3C TraceContext compliance

Implement W3C TraceContext and get 100% pass rate from the validation service https://github.com/w3c/trace-context/tree/master/test.

CI should be implemented which verifies the TraceContext compliance.

Moving to GA milestone, as fix doesn't involve api/sdk interface changes. And few of the failures are related to issues with the test suite used for validation.
