func FilterByHost 

func FilterByHost(host, hostNamespace, serviceName, svcNamespace string) bool

FilterByHost returns true if a (host, hostNamespace) combination is making reference to a (serviceName, svcNamespace) combination. Presumably, the host is part of the definition of some Istio Resource. Thus, it can take the form of "host", "host.namespace" or "host.namespace.svc", or the FQDN "host.namespace.svc.<identity_domain_suffix>". For the cases where the host argument takes the simplistic form of only "host", you need to provide the hostNamespace argument, which should be set to the namespace of the involved Istio Resource. For the other cases, it is safe to omit it. The other arguments are always mandatory.
