This longer form address that allows specifying `.peer` would need to be used for tproxy DNS requests made within non-default partitions for imported services.

* config-entry: Validate that service-resolver `Failover`s and `Redirect`s only
specify `Partition` and `Namespace` on Consul Enterprise. This prevents scenarios
where OSS Consul would save service-resolvers that require Consul Enterprise. [[GH-14162](https://github.com/hashicorp/consul/issues/14162)]
