The scheduler API 'get_pools' was copied from Cinder and has several
problems. The REST endpoint, /scheduler-stats/get_pools, is not a
REST-appropriate name. The API allows filtering but filters are not
currently supported by the Manila scheduler. The API was added as an
extension, not part of the v1 API as it should be. After restarting
the scheduler service, the API doesn't return any data until a share
has been created (Cinder was used as a model for fixing this one).
This patch fixes all of these issues.
