        Description copied from class: Sampler
        Called during Span creation to make a sampling decision.
        Specified by:
        shouldSample in class Sampler
        Parameters:
        parentContext - the parent span's SpanContext. null if this is a root span.
        hasRemoteParent - true if the parent Span is remote. null if this is a root span.
        traceId - the TraceId for the new Span. This will be identical to that in the parentContext, unless this is a root span.
        spanId - the SpanId for the new Span.
        name - the name of the new Span.
        parentLinks - the parentLinks associated with the new Span.
        Returns:
        true if the Span is sampled.
