How Has This Been Tested?

1. Dependency tree check: confirms CXF is no longer resolved for the KVM plugin module:
   mvn dependency:tree -pl plugins/hypervisors/kvm -Dincludes=org.apache.cxf
   output is empty after the fix

2. Build artifact check: confirms no CXF jars are copied into the agent's dependency bundle
   ls plugins/hypervisors/kvm/target/dependencies | grep -i cxf
   no result
