We currently ignore the spec.addons.<addon>.install.service.ingress.hosts field for Kiali and Jaeger add-ons. This issue is about implementing it.

From https://docs.google.com/document/d/13Z7IPQRXVIWGpFzqU9woRT_nr1bE8mcs1Nvq_2rrvkk/edit#heading=h.m8306jv8lurg

Kiali only supports a single host, so we need validation to fail if users try to use >1 host

Acceptance Criteria:

• support setting ingress.hosts on Routes for Kiali and Jaeger
  • Kiali can only do a single host, so validation should catch it if you're trying to configure more
• operator unit test
