Backendtlspolicy hostname should be optional #4011
Description
It would be nice to have the hostname field optional, with the semantic that if under the natural hostname of the backend will be used. For example, for a service this may be name.ns.svc.cluster.local.
this avoids the need for a user to attempt to repeat the same information in two places which is error prone and tedious.
This should NOT mean hostname is not validated; if the backend does not have a valid hostname to default to, it should be rejected
