sampler and span processor prototype implementations for consistent sampling (#226)
* sampler and exporter implementations for consistent sampling
* improved dependencies (in particular, removed dependency on guava)
* Update consistent-sampling/src/main/java/io/opentelemetry/contrib/samplers/ConsistentParentBasedSampler.java
Co-authored-by: Anuraag Agrawal <anuraaga@gmail.com>
* reverted some changes
* removed wrong immutable annotation
* added javadoc
* avoid else statements when returning
* factory methods for consistent samplers, avoid exposure of implementations
* added javadoc for AND and OR sampler composition
* replaced use of synchronized by atomic reference
* simplified thread local initialization
* removed consistent reservoir sampling
* improved comment
* removed unnecessary clipping of sampling probability
* added javadoc explaining maths of implementation
* Update consistent-sampling/src/main/java/io/opentelemetry/contrib/state/OtelTraceState.java
