Bug: Changing annotation `disco/record` does not delete the old record from Designate

[IvoGoman]

Initially, I had added the following annotations to a service of type LoadBalancer:

metadata:
  annotations:
    disco: "true"
    disco/record: myhost.zone.tld.
    disco/record-type: A

The A record was successfully created in designate.

Then I realised the record needed to be prefixed with ingress.

metadata:
  annotations:
    disco: "true"
    disco/record: ingress.myhost.zone.tld.
    disco/record-type: A

DISCO now updated the Record CR in the cluster and created a new Record in Designate. However, the old record without the ingress prefix was abandoned by the controller.

My expectation would have been that DISCO removes the first record as well as, creating the new record.
