func (t *MOTracer) Start(ctx context.Context, name string, opts ...trace.SpanStartOption) (context.Context, trace.Span)

Start starts a Span and returns it along with a context containing it.

The Span is created with the provided name and as a child of any existing span context found in passed context. The created Span will be configured appropriately by any SpanOption passed.

Only timeout Span can be recorded, hold in SpanConfig.LongTimeThreshold. There are 4 diff ways to setting threshold value: 1. using default val, which was hold by MOTracerProvider.longSpanTime. 2. using `WithLongTimeThreshold()` SpanOption, that will override the default val. 3. passing the Deadline context, then it will check the Deadline at Span ended instead of checking Threshold. 4. using `WithHungThreshold()` SpanOption, that will override the passed context with context.WithTimeout(ctx, hungThreshold) and create a new work goroutine to check Deadline event.

When Span pass timeout threshold or got the deadline event, not only the Span will be recorded, but also trigger profile dump specify by `WithProfileGoroutine()`, `WithProfileHeap()`, `WithProfileThreadCreate()`, `WithProfileAllocs()`, `WithProfileBlock()`, `WithProfileMutex()`, `WithProfileCpuSecs()`, `WithProfileTraceSecs()` SpanOption.
