Anthony Mirabella ca3f74d976 Add Span#RecordError method to simplify adding error events to spans (#473) ... * Add `Span#Error` method to simplify setting an error status and message. * `Span#Error` should no-op on nil errors * Record errors as a span event rather than status/attributes. The implementation in the SDK package now relies on existing API methods. * Add WithErrorStatus() ErrorOption to allow setting span status on error. * Apply suggestions from code review Co-Authored-By: Krzesimir Nowak <qdlacz@gmail.com> * Address code review feedback * Clean up RecordError tests * Ensure complete and unique error type is recorded for defined types * Avoid duplicating logic under test in tests * Move TestError to internal/testing package, improve RecordError test scenarios Co-authored-by: Krzesimir Nowak <qdlacz@gmail.com>		2020-02-28 13:44:53 -08:00
