Describe the enhancement
False positive fault raised for "[Check 12/89] Post Upgrade Callback Integrity".
The enhancement request is to evaluate if a validation logic optimization is possible to reduce false positives.

Current behavior/output
Before APIC upgrade:

[Check 12/89] Post Upgrade Callback Integrity... Re-run script after APICs are upgraded and back to Fully-Fit  POST UPGRADE CHECK REQUIRED

After APIC upgrade:

[Check 12/89] Post Upgrade Callback Integrity...                                 FAIL - OUTAGE WARNING!!
  Missed Objects  Impact
  --------------  ------
  fvSlaDef        IPSLA monitor policy will not be deployed

  Recommended Action: Contact Cisco TAC with Output
  Reference Document: https://datacenter.github.io/ACI-Pre-Upgrade-Validation-Script/validations/#post-upgrade-callback-integrity

The Findings:
moquery returns different object counts for the old and new classes(fvIPSLAMonitoringPol/fvSlaDef).
The command "moquery -c fvSlaDef -x rsp-subtree-include=count" shows a count of 2, even though only one default fvSlaDef exists, which appears to be an incorrect count. This count mismatch appears to trigger the Post Upgrade Callback Integrity warning.
