Add support for SpanLinks

[bidetofevil]

Goal

Add basic support for SpanLinks. A couple of things still have to be finalized:

• Payload shape
• Limits

Thought I'd get this in review first and made the approach changes after

Testing

Unit and integration tests added

LGTM pending discussion with folks on other SDKs about what the payload & behavior of limits should look like
