Kiali doesn't trust the CA for login.dso.mil

When enabling SSO for kiali against the login.dso.mil keycloak as below, receive a cert trust error in the logs and unable to log in, however this works fine against a local keycloak instance (keycloak.dev.bigbang.mil).

Use steps here to deploy, updating overrides as needed to enable Kiali SSO.

Investigate and implement necessary changes to correct the trust issue.
