Part of #6408, please read that first.

The dependency exists in OTEL/contrib/extension/jaegerremotesampling. It might be relatively easy to break, but need to try it out.

• Copy whichever code is needed from cmd/collector/app/sampling and plugin/sampling/strategyprovider/static to OTEL/contrib.
• Refactor Jaeger code internally so that these modules are hidden under some /internal/ package (discuss options/proposals on this ticket first)
