Consistent sampling

This component adds various Sampler implementations for consistent sampling as defined by https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/tracestate-probability-sampling.md and https://github.com/open-telemetry/opentelemetry-specification/pull/2047.

ConsistentSampler: abstract base class of all consistent sampler implementations below
ConsistentAlwaysOffSampler: see https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/tracestate-probability-sampling.md#always-off-sampler
ConsistentAlwaysOnSampler: see https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/tracestate-probability-sampling.md#always-on-consistent-probability-sampler
ConsistentComposedAndSampler: allows combining two consistent samplers and samples when both samplers would sample
ConsistentComposedOrSampler: allows combining two consistent sampler and samples when at least one of both samplers would sample, see https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/tracestate-probability-sampling.md#requirement-combine-multiple-consistent-probability-samplers-using-the-minimum-p-value
ConsistentParentBasedSampler: see https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/tracestate-probability-sampling.md#parentconsistentprobabilitybased-sampler
ConsistentProbabilityBasedSampler: see https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/tracestate-probability-sampling.md#consistentprobabilitybased-sampler
ConsistentRateLimitingSampler: a rate limiting sampler based on exponential smoothing that dynamically adjusts the sampling probability based on the estimated rate of spans occurring to satisfy a given rate of sampled spans
