<pre>
A list of backupCollections in the project.

If the `location_id` in the parent field of the request is "-", all regions
available to the project are queried, and the results aggregated.
If in such an aggregated query a location is unavailable, a placeholder
backupCollection entry is included in the response with the `name` field
set to a value of the form
`projects/{project_id}/locations/{location_id}/backupCollections/`- and the
`status` field set to ERROR and `status_message` field set to "location not
available for ListBackupCollections".
