…y. Prior to this change `createSpan` would create a new SpanOptions, out of a OperationTracingOptions (basically). This works today but will break when we move to a later version of opentelemetry, where the necessary information to track is actually two separate fields.

To make this simpler we have a createSpanFunction that can handle doing the proper updating of the `tracingOptions ` property of an OperationOptions compatible type. Converting any code over to this style should future proof us a bit.

In storage-blob the changes I've made here are:
- If the call takes an OperationOptions, try to pass the updatedOptions directly, or if extensive copying/mutation was occuring - just pass operationOptions.tracingOptions instead.

So this code:

```
          {
              ...options,
              tracingOptions: { ...options!.tracingOptions, spanOptions }
            }
```

Becomes

```
updatedOptions (which came back from core-tracing's createSpan function)
```

- If the underlying call takes RequestOptionsBase then we call ...convertTracingToRequestOptionsBase(updatedOptions) which should allow me room to just change _that_ function when the number of fields to copy over changes.
