typo in external_ceph.yml

Deploying using kolla-ansible with external Ceph cluster.

TASK [nova : Check cinder keyring file] ****************************************
fatal: [dl004]: FAILED! => {"failed": true, "msg": "The module state was not found in configured module paths. Additionally, core modules are missing. If this is a checkout, run 'git submodule update --init --recursive' to correct this problem."}

typo appears to be in:

kolla-ansible/ansible/roles/nova/tasks/external-ceph.yml

  local_action: state path="{{ node_custom_config }}/nova/ceph.client.cinder.keyring"

corrected to:

- name: Check cinder keyring file
  local_action: stat path="{{ node_custom_config }}/nova/ceph.client.cinder.keyring"
  register: cinder_cephx_keyring_file
  failed_when: not cinder_cephx_keyring_file.stat.exists
  when: cinder_backend_ceph | bool

results in:

TASK [nova : Check cinder keyring file] ****************************************
ok: [dl004 -> localhost]
