With the change to allow volumes to dynamically grow we need to define
the default volume size to contain a valid size modifier. At present the
value is creating a sparse file that is 1024 bytes. This change sets the
size to gigabytes.
The role pin is updated to include the changes in the lxc_hosts role
which use this method of configuration. Without it the quota setting
end up with a GG at the end, which is invalid and the command fails.
