Improve manage volume

Registered by Yusuke Hayashi on 2016-10-22

Currently, manage-volume requires at least twice getting volume information from a storage.
(1. get size for quota, 2. get other volume information)

It is inefficient for some storages which take almost same time to offer size / detailed volume info.
This bp improves this logic by adding bypass between manage_existing and manage_existing_get_size.
