list method
Lists Certificates in a given project and location.
Request parameters:
parent - Required. The project and location from which the certificate
should be listed, specified in the format projects / * /locations / * .
Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+$.
filter - Filter expression to restrict the Certificates returned.
orderBy - A list of Certificate field names used to specify the order of
the returned results. The default sorting order is ascending. To specify
descending order for a field, add a suffix " desc".
pageSize - Maximum number of certificates to return per call.
pageToken - The value returned by the last ListCertificatesResponse.
Indicates that this is a continuation of a prior ListCertificates call,
and that the system should return the next page of data.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListCertificatesResponse.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
