In a previous PR open-telemetry#1657 the lambda behaviour was changed so that it extracs the context from the headers of the lambda event instead of from the lambda runtime, using the _X_AMZN_TRACE_ID env var. This behaviour is undesireble as it is a breaking change to existing users. This PR will add the previous behaviour through an opt-in flag so that users can be gracefully migrated or these two "modes" of operation can exist without conflict.

There was a problem hiding this comment.
I think this config name is misleading. Per open-telemetry/opentelemetry-specification#3212, x-ray propagation should often be used. The issue at hand is specific to the environment variable.

Description
In a previous PR #1657 the lambda behaviour was changed so that it extracs the context from the headers of the lambda event instead of from the lambda runtime, using the _X_AMZN_TRACE_ID env var.
This behaviour is undesireble as it is a breaking change to existing users.
This PR will add the previous behaviour through an opt-in flag so that users can be gracefully migrated or these two "modes" of operation can exist without conflict.
