Special character between trace context fieds

[bogdandrutu]

One of the request was to add an extra human-readable character between the trace context fields. The current proposal was to not have this extra character.

Proposal to use '-' character between version/trace_id/span_id/options:
Value = 00-4bf92f3577b34da6a3ce929d0e0e4736-00f067aa0ba902b7-01000000

This proposal will allow SREs to easily copy-paste or parse the trace-id/span-id/options if needed.

In skywalking, we use '|' to split right now. Here is a sample context:

trace_id_A|100|REMOTE_APP|10.2.3.16:8080|Trace.global.id.123|1

trace_id and Trace.global.id include '.' and '-' , and that is why we choice '|' at first place.

We definitely can support this with tiny changes, after this spec is settled and people can get benefits from these changes.

This issue is really old. Should we mark it as resolved?

Agree needs to be resolved. I'll close it for now
