[FEATURE]: Span cancellation #257
Description
Describe the goal of the feature
Ability to "cancel" a dd:Span that has been created such that it does not appear in the APM traces.
Sometimes a dd::Span I have created no longer makes semantic sense due to errors or other edge conditions that are not present at the time the Span is created.
For example I have a "time to receive first data" span within a proxy which clutters the traces when there are subsequent errors preventing data being received.

Describe alternatives you've considered
It would be possible to implement this by wrapping dd::Span in my own span class and using dd::SpanConfig::start in conjunction with dd::Span::set_end_time().
