Notification for a key of volume type is not good enough

[Hiroyuki Eguchi]

Following events are notified when a key of volume type is changed.
 - volume_type_extra_specs.create
 - volume_type_extra_specs.delete

However, These notifications doesn't include date fields (e.g. created_at, updated_at).
Notifications are often used by external system for searching(e.g. searchlight) or analyzing.
So, we have to notify all the information they need.
Date information is very important for external system to search or analyze.
