Temporary workaround

Disable the command creating the SSH key which already exists since 6months on hetzner (snowdrop)

#- name: "Create cloud server key"
#  shell: "hcloud ssh-key create --name {{ context_name }} --public-key \"{{ hetzner_public_key }}\""
#  register: hcloud_ssh_key_res
#  changed_when: "hcloud_ssh_key_res.rc == 0"
#  failed_when: "hcloud_ssh_key_res.rc != 0 and ('SSH key with the same fingerprint already exists' not in hcloud_ssh_key_res.stderr)"
