Unify API Span Start/End Options (#1108)
* Unify API Span Start/End Options

Replace both with `SpanOption`. Add a unified `SpanConfig` to match and
a `SpanConfigure` function to parse a `SpanConfig` from `SpanOption`s.

Update all the related options to use new `SpanOption`s.

* No non-zero SpanConfig defaults

The SDK uses an internal clock for the current time that cannot be use
if it does not know the time has not been set.

* Append attributes for WithAttributes

This preserves existing behavior.

* Add unit test for SpanConfigure

* Propagate changes

* Update append option documentation

* Update testing comments

* Move comments on guarantees to appropriate function

* Add documentation for SDK methods

Include SDK implementation specific information in the Tracer Start
method and Span End method.

* Add changes to Changelog

* Apply suggestions from code review

* Update the SpanKind comment in the  SpanConfig

Try for a less tautological comment.
