About RateLimitSampler and GuaranteedThroughputProbabilisticSampler

[j2gg0s]

Do we have any plan to add RateLimitSampler and GuaranteedThroughputProbabilisticSampler

Like in jaeger:

I'm personally in favor of an unbiased Sampler that can attach concrete probabilities to the SpanData that it emits. Neither of these Samplers can do that.

I made a comment about how a Sampler can be unbiased, emit probabilities, and limit throughput here: open-telemetry/opentelemetry-specification#570 (comment)
