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.
The new module will allow users to control LXC containers from ansible.
The module was built for use in LXC >= 1.0 or greater and implements most
of what can be done using the various lxc clients with regards to running
containers. This first module is geared only at managing lxc containers.
The module provides:
build containers
destroy containers
archive containers
info from a single container
start / stop / restart containers
run commands within containers
add/modify lxc config for a container
supports backends including LVM
