  To reset the entire DB parameter group, specify the <code>DBParameterGroup</code> name and
  <code>ResetAllParameters</code> parameters. To reset specific parameters, provide a list of the following:
  <code>ParameterName</code> and <code>ApplyMethod</code>. A maximum of 20 parameters can be modified in a single
  request.
