list method
Lists information about the supported locations for this service.
Request parameters:
name - The resource that owns the locations collection, if applicable.
Value must have pattern ^projects/\[^/\]+$.
filter - A filter to narrow down results to a preferred subset. The
filtering language accepts strings like "displayName=tokyo", and is
documented in more detail in [AIP-160](https://google.aip.dev/160).
pageSize - The maximum number of results to return. If not set, the
service selects a default.
pageToken - A page token received from the next_page_token field in
the response. Send that page token to receive the subsequent page.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListLocationsResponse.
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.
