When trying to use basic auth, thus no keystore or trustore configured and trying to connect to a service via REST next exception is thrown

"status": {
 "code": 500,
 "eventType": "EVENT_COMPONENT_FAILURE",
 "timestamp": "2021-03-23T15:43:15.427Z",
 "errorMessage": "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target",
 "message": "failure"
 },

This was resolved in Honolulu by making BasicAuthRestClientService trust all certificates.  HOWEVER, this violates a Global Requirement expected in Istanbul, which forbids disabling host name verification.
