Split the container and host variable files
The host and container image variable files have been split. This split now gives deployers the ability to change or customize the container image used on a given host. Change-Id: I839bbcfff3f33dde144e9fb8d078fa1d97f8c410 Signed-off-by: Kevin Carter <kevin.carter@rackspace.com>

closely associated with the underlying OS however should a deployer need,

this option can be used to customize the base container image for a given
