title: How to clean users associated with SSH Metadata on GCE instances?
body: <p>Does anyone know how to clean  users associated with SSH Metadata on GCE instances? Not sure I am asking the question correctly/clearly. Interestingly, I could use <code>gcloud compute ssh</code> login as any user which never existed before. After login as any non-existing user, next time this user will be added to any new VM. Because of a typo, I have some users I don't want to have when a new instance is created.</p>
