fix: Set EMF metrics key correctly

It lives in the "CloudWatchMetrics" subdictionary, not in the "_aws" root dictionary. This was prevening metrics from showing up in the correct namespace in the cloudwatch web interface (they were listed under "local" instead of "PerfTests"). Signed-off-by: Patrick Roy <[email protected]>
