Is it possible to add a key to the Certificate Authority?

[DeepZeepOk]

If not, is there any plan to add this feature?

I don't have a need for it so it's not high on my priority list. PRs are welcome though.

Are you looking for the equivalent of the "create internal CA" web configuration, or something different?

If this is related to the possibility to import a CA with a private key, it can be simply implemented :
In _validate_params

if params['key'] is not None:
      ca_key = params['key']
      lines = ca_key.splitlines()
      if lines[0] == '-----BEGIN PRIVATE KEY-----' and lines[-1] == '-----END PRIVATE KEY-----':
          params['key'] = base64.b64encode(ca_key.encode()).decode()
      elif not re.match('LS0tLS1CRUdJTiBQUklWQVRFIEtFWS0tLS0t', ca_key):
          self.module.fail_json(msg='Could not recognize CA key format: %s' % (ca_key))

And in _params_to_obj:

if 'key' in params and params['key'] is not None:
      obj['prv'] = params['key']
