list method
List configurations.
Results are sorted by creation time, descending.
Request parameters:
parent - The namespace from which the configurations should be listed.
For Cloud Run, replace {namespace_id} with the project ID or number.
Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+$.
continue_ - Optional. Encoded string to continue paging.
fieldSelector - Not supported by Cloud Run.
includeUninitialized - Not supported by Cloud Run.
labelSelector - Allows to filter resources based on a label. Supported
operations are =, !=, exists, in, and notIn.
limit - Optional. The maximum number of the records that should be
returned.
resourceVersion - Not supported by Cloud Run.
watch - Not supported by Cloud Run.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListConfigurationsResponse.
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.
