Changes

Updates Trace SDK and Propagator specifications with

  • List W3C propagator requirements (e.g., should propagate tracestate)
  • Introduce W3C Trace Context Level 2 w/ the Random flag
  • Define explicit randomness feature from OTEP 235, OTEP 261
  • Trace SDK default ID generator should include 56 bits of randomness in the correct location
  • Trace SDK for root spans: either set the random flag to confirm the above, or use an explicit randomness value.

Part of #1413.
Part of #3602.

Product of the Sampling SIG members @kentquirk @kalyanaj @oertl @PeterF778 @yuanyuanzhao3 and myself.

LGTM, I don't see anything contentious in this PR. I'd probably prefer having a bit more context on the example shown in the PR, but that's not strictly necessary.
