  Lists all your signing jobs. You can use the <code>maxResults</code> parameter to limit the number of signing
  jobs that are returned in the response. If additional jobs remain to be listed, AWS Signer returns a
  <code>nextToken</code> value. Use this value in subsequent calls to <code>ListSigningJobs</code> to fetch the
  remaining values. You can continue calling <code>ListSigningJobs</code> with your <code>maxResults</code>
  parameter and with new values that AWS Signer returns in the <code>nextToken</code> parameter until all of your
  signing jobs have been returned.
