          Update a certificate issuer. <br> **Example usage:**  ``` curl -X PUT \\ -H 'authorization: <valid access token>' \\ -H 'content-type: application/json;charset=UTF-8' \\ https://api.us-east-1.mbedcloud.com/v3/certificate-issuers/01621560be51507b9d48a91b00000000 \\ -d '{   \"description\": \"Sample GlobalSign certificate issuer - updated.\",   \"name\": \"GlobalSign Issuer\" }' ```   # noqa: E501
          This method makes a synchronous HTTP request by default. To make an
          asynchronous HTTP request, please pass asynchronous=True
          >>> thread = api.update_certificate_issuer(certificate_issuer_id, certificate_issuer_update_request, asynchronous=True)
          >>> result = thread.get()
  
          :param asynchronous bool
          :param str certificate_issuer_id: Certificate issuer ID. <br> The ID of the certificate issuer.  (required)
          :param CertificateIssuerUpdateRequest certificate_issuer_update_request: Certificate issuer update request. (required)
          :return: CertificateIssuerInfo
                   If the method is called asynchronously,
                   returns the request thread.
