OSSM Trust domain configuration is not working
When I tested SMCP trust domain configuration, reference [1], the httpbin app always return 503 after I changed the trust domain to old-td

[1] https://istio.io/v1.9/docs/tasks/security/authorization/authz-td-migration/

I deployed httpbin in foo ns and sleep in foo ns, bar ns.
SMCP spec change : spec.security.trust.domain=old-td

test script: https://github.com/maistra/maistra-test-tool/blob/maistra-2.1/pkg/tasks/security/authorization/trust_domain.go

Expected behavior : after trust domain migrates to old-td. sleep in foo ns should curl a httpbin and gets 403. sleep in bar ns should curl a httpbin and gets 200
