* Refactor SDK Sampler API to conform to Spec * Sampler is now an interface rather than a function type * SamplingParameters include the span Kind, Attributes, and Links * SamplingResult includes a SamplingDecision with three possible values, as well as Attributes * Add attributes retruned from a Sampler to the span * Add SpanKind, Attributes, and Links to API Sampler.ShouldSample() parameters * Drop "Get" from sdk Sampler.GetDescription to match api Sampler * Make spanID parameter in API Sampler interface a core.SpanID * Fix types and printf format per PR feedback from krnowak * Ensure unit test error messages reflect new reality Co-authored-by: Joshua MacDonald <jmacd@users.noreply.github.com>
