Fixes #1708
To maintain backward compatibility,
SamplingResultwill default tonullforTraceStateString. Any non-null value set by samplers, will be set as the tracestate of the created activity.If sampler intents to not modify tracestate, it can return null. (Default)
Else, it can populate tracestate with desired value.
Given tracestate is implemented as a opaque string, the samper is responsible for ensuring the tracestate semantics are followed.
