feat(shim-opentracing): add propagator configuration

[vreynolds]

Which problem is this PR solving?

• New spec outlines an optional propagator configuration for OpenTracing TEXT_MAP and HTTP_HEADERS formats
  • https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/compatibility/opentracing.md#create-an-opentracing-tracer-shim
  • https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/compatibility/opentracing.md#tracer-shim
• Updates Update the OT Shim layer #2030

Short description of the changes

• optional propagator config based on new spec
  • leaving binary format as is, since that's not (yet?) specified in the spec
  • existing behavior: unknown format is a NOOP
  • changes are additive (non-breaking)
• remove outdated note from readme: Add baggage support to the opentracing shim #329
• fix jsdoc links: import was changed from types --> api
