          Delete a certificate issuer by ID. <br> **Example usage:**  ``` curl -X DELETE \\ -H 'authorization: <valid access token>' \\ https://api.us-east-1.mbedcloud.com/v3/certificate-issuers/0162155dc77d507b9d48a91b00000000 ```   # noqa: E501
          This method makes a synchronous HTTP request by default. To make an
          asynchronous HTTP request, please pass asynchronous=True
          >>> thread = api.delete_certificate_issuer(certificate_issuer_id, asynchronous=True)
          >>> result = thread.get()
  
          :param asynchronous bool
          :param str certificate_issuer_id: Certificate issuer ID. <br> The ID of the certificate issuer. An active certificate issuer may not be deleted.  (required)
          :return: None
                   If the method is called asynchronously,
                   returns the request thread.
