    [pulsar-broker] Security-Recommendation: Remove verbose error message with 
system info for admin-api (#8454)
    
    ### Motivation
    
    one of the security-recommendation report has listed system internal info 
in error-response which should be fixed.
    
    **url:** `curl -X DELETE -H 'Content-Type: application/json'  
http://localhost:8080/admin/namespaces/sample/standalone/ns1/maxConsumerPerSubscription`
    **Error-response:**
    ```
     --- An unexpected error occurred in the server ---
    
    Message: Invalid bundle range
    
    Stacktrace:
    
    java.lang.IllegalArgumentException: Invalid bundle range
