Set default Propagators list and bash script flags

We want the default propagators to include both w3c context and xray, so set `OTEL_PROPAGATORS=tracecontext,baggage,xray` if it isn't already set to something else. Users that send traces to X-Ray, especially if they enable Active Tracing, should override this value to `OTEL_PROPAGATORS=tracecontext,baggage,xray-lambda` to ensure proper span relationships. I also added some common bash flags to align with industry standard practice.
