Volume size units should be in GiB, not GB

[Richard Hagarty]

Data size on storage devices is typically measured in GiB (2^30), and not GB (10^9).

The Cinder community has addressed this issue by changing all of their CLI and Horizon panels to use "GiB"
(see https://bugs.launchpad.net/horizon/+bug/1511167)

There are several Nova panels that display/request data sizes that should also be changed for consistency:
Project -> Instances -> Launch Instance
Project -> Instances -> table colums
Admin -> Flavors -> Create Flavor
Admin -> Flavors -> table columns

according to descriptions, seems this is a horizon bug

[Richard Hagarty (richard-hagarty)]

@jichenjc - agree that this specific defect is a horizon bug, but I was hoping to first get the nova community to agree that this was really an inconsistency and that it should be fixed. Also, maybe get the some nova folks to examine their API and CLI to ensure they are consistent in regards to the GB vs GiB storage size issue.

Fix in Horizon needs to follow any changes in Nova (see https://bugs.launchpad.net/python-novaclient/+bug/1521791)

Since there doesn't appear to be any progress on the nova bug, I will unassign myself for now.

Looking at the description and the comment on the abandoned patch(https://review.openstack.org/#/c/290329/), I think this is an invalid defect.

As was pointed out in the patch mentioned above, Flavors are measured in GB, not GiB.
