chore(tracing): remove deprecated properties and parameters

[mabdinur]

• Introduces the following breaking changes to tracing components:
  • Removes deprecated parameters from Tracer.configure(...) method and removes the Tracer.sampler attribute.
  • Drops support for multiple tracer instances, ddtrace.trace.Tracer can not be reinitialized.
  • Removes the deprecated Span.sampled property
  • Drops support for configuring sampling rules using functions and regex in the
    ddtrace.tracer.sampler.rules[].choose_matcher(...) method
    and removes the timestamp_ns parameter from ddtrace.internal.rate_limiter.RateLimiter.is_allowed().
  • Drops support for configuring DD_TRACE_METHODS with the '[]' notation. Ensure DD_TRACE_METHODS use the ':' notation instead".
  • Removes the deprecated ddtracer parameter from ddtrace.opentracer.tracer.Tracer().
