In Lambda custom runtimes propagate the tracing header (Lambda-Runtime-Trace-Id) to env. _X_AMZN_TRACE_ID

One of the steps described in Custom AWS Lambda Runtimes:

Propagate the tracing header – Get the X-Ray tracing header from the Lambda-Runtime-Trace-Id header in the API response. Set the _X_AMZN_TRACE_ID environment variable with the same value for the X-Ray SDK to use.

Setting Environment variables in Java is not supported and I don't think we should use any of the hack workarounds.

Moreover it seems AWS XRAY SDK does not support it either.

Hi, it looks like we can propagate it through the 'setProperty()' now. Could we consider this approach?
