• removing Tracer's startChildSpan(name?: string, kind?: types.SpanKind) interface

Old code

// Multi argument interface
const span = tracer.startChildSpan('my-span', types.SpanKind.SERVER);

// Or options object interface
const span = tracer.startChildSpan({
  name: 'my-span',
  kind: types.SpanKind.SERVER
});

New code

// Only options object interface is supported
const span = tracer.startChildSpan({
  name: 'my-span',
  kind: types.SpanKind.SERVER
});
