There was a problem hiding this comment.
can we add better test for this logic:

Description of your changes
In #1070 customers have requested the addition of a new method in Tracer that allows to access the AWS X-Ray Root Trace ID. This is useful in those situations in which customers want to use this id as correlation id in the responses returned by a function or manually pass it to downstream processes.
The logic to retrieve and parse this ID was already present in Logger (here). For that utility we use the method to append the
xray_trace_idto log entries in some cases.During the discussion of the feature it became clear that this could be a good moment to also extract this logic to the
commonspackage continuing the work started in #484, and potentially unlocking/facilitating #165.Before this change
After this change
This issue also introduces a new public method in Tracer called
getRootXrayTraceIdthat allows customers to access the AWS X-Ray Root Trace ID within a Lambda handler.Fixes #1070
