Support for ResourceARN rules in XRAY sampling

I've been trying to filter out my Zappa keep_warm scheduled task, which always comes from the same resource ARN, I thought my sample rules were broken until I realised that the AWS XRAY SDK doesn't support this type of rule.

It's incredibly frustrating to have this automated keep warm tasks registering as user interaction, as my xray console map shows every lambda as being accessed by a user even when they are not available to the public, and only for API consumption.

El issue no menciona archivos ni pruebas; empieza localizando el manejo de las reglas de sampling del SDK y revisando cómo se representan las reglas ResourceARN de AWS X-Ray. Se considera terminado cuando las reglas ResourceARN pueden excluir la tarea programada reportada y el comportamiento está cubierto por una verificación de las decisiones de sampling.
