Optional size parameter for snapshot and clone

[Juan Manuel Ollé]

When creating a volume from snapshot or cloning it the size parameter should be optional.

cinder create --snapshot-id 5eebad73-420f-4880-9526-333f768a3fc7

Interesting. You are correct that the command fails if no size is given to the command. It appears that the size parameter is allowed so that the user can create a volume from the snapshot that is larger than the original. It properly prevents you from creating a volume of a lesser size than the snapshot. I guess I can see that the option is somewhat unnecessary if you don't want to change the size of the new volume.

I am going to call this a wishlist item as it isn't really a bug, but seems like something we could change.
