New YAML defined for ACS DT v3.x plus
- check-sr-results.yaml used for IR 2.x is renamed to check-sr-results-ir2.yaml
- new check-sr-results-dt3.yaml defined for DT v3.x onward
- Relaxed sanity checks from dt3.yaml which are not affecting compliance
- tweaked test-check-sr-results to skip sniff and capsule checks for dt3.yaml
