connect: wildcard services in IGCE more restricted than consul

[shoenig]

This ingress gateway configuration entry is allowed by Consul, exposing all services through the listener and allowing omission of the Hosts field.

Kind = "ingress-gateway"
Name = "my-ingress-service"
Listeners = [
  {
    Port     = 9090
    Protocol = "http"
    Services = [
     {
       Name = "*"
     }
   ]
  }
]

Nomad doesn't respect the wildcard behavior, instead asserting one or more hosts must be defined when using http protocol. Nomad should behave like Consul here.
