Search all IAM policies request.
.. attribute:: scope
Required. A scope can be a project, a folder or an
organization. The search is limited to the IAM policies within
the scope. The allowed values are: -
projects/{PROJECT_ID} - projects/{PROJECT_NUMBER} -
folders/{FOLDER_NUMBER} - organizations/{ORGANIZATION_NUMBER}
Optional. The page size for search result pagination. Page
size is capped at 500 even if a larger value is given. If set
to zero, server will pick an appropriate default. Returned
results may be fewer than requested. When this happens, there
could be more results as long as next_page_token is
returned.
