ZoneV2 Observe Only Resource doesn't work with zone name

Hello,

I'm trying to import an existing DNS zone so that I can create recordsets and refer to the already existing zone.

` apiVersion: dns.openstack.crossplane.io/v1alpha1
kind: ZoneV2
metadata:
name: my-zone
annotations:
crossplane.io/external-name: domain.example.com
spec:
managementPolicies: ["Observe"]
forProvider: {}`

Instead of working, this happens:

`Error: Error retrieving openstack_dns_zone_v2 domain.example.com: Bad request with: [GET https://my-openstack:9001/v2/zones/domain.example.com], error message: {"code": 400, "type": "invalid_uuid", "message": "Invalid UUID zone_id: domain.example.com", "request_id": "req-ec855967-93b1-4706-92b4-9d2e6107e341"}`

Of course, if the name is replaced with the zone ID it works, though that sort of defeats the purpose. In my use case the name is known, the ID is not.
