Updated volume create methods for a more consistent process

Browse source 
The volume create methods were making an assumption on the unit
sizes being presented by the `vgdisplay` and the `lvdisplay`
commands. To correct the assumption the commands will now enforce
a unit size of "g" which will alway convert sives to gigabytes.
This was an issue brought up by @hughsaunders.
