fix: support new x ray format nodejs

[sagivoululumigo]

Fixes Issue

AWS is planning on releasing a change to the format of the X-Ray Trace ID value, and we need to support the new format (And the old one to support the transition phase).

AWS is removing the Parent and Sampled fields from any lambda that is set to passive tracing (the default). The old format is:

Root=1-5759e988-bd862e3fe1be46a994272793;Parent=53995c3f42cd8ad8;Sampled=1;Lineage=a87bd80c:1|68fd508a:5|c512fbe3:2

And the new format will be:

Root=1-5759e988-bd862e3fe1be46a994272793;Lineage=a87bd80c:1|68fd508a:5|c512fbe3:2

Notes:

• We use the Root value for the transaction id value (The last part splitting by -)
• We don't use the Parent field in the tracer code for anything except adding it to the lambda invocation http span traceId json. The python tracer doesn't add this field to the span, so I suspect it isn't used
• Parsing the x ray trace-id is crucial for the tracer to work, we had a bug with this parsing a year ago that caused the customers lambda to crash once the traceId format changed... need to be carful here
