Add new notifications types for volumes/snapshots
=================================================
https://blueprints.launchpad.net/ceilometer/+spec/add-new-notifications-types-for-volumes-and-snapshots
Now we have only two types of notifications about volumes/snapshots:
volume/snapshot existence and their size.
This change allows to collect and view notifications of different types.
We can get information about which events have occurred: volume/snapshot has
been created or deleted or updated(renamed or modified description), volume
has been resized or attached/detached. This will allow to process additional
events and will improve the overall Ceilometer functionality.
Problem description
===================
Now we have only two types of notifications about volumes/snapshots:
volume/snapshot existence and their size. But there is no information about
events like volume/snapshot was created or deleted or updated or volume was
resized or attached/detached.
Proposed change
===============
This change allows to collect and view notifications of different types -
volume/snapshot.create.start, volume/snapshot.create.end,
volume/snapshot.delete.start, volume/snapshot.delete.end,
volume/snapshot.update.start, volume/snapshot.update.end,
volume.resize.start, volume.resize.end,
volume.attach.start, volume.attach.end,
volume.detach.start, volume.detach.end.
