This change was made to improve ansible stability and speed.
Additionally this change comes with the now upstream lxc-container
module which will allow us to drop our carried module. In dropping
the module the entry point was changed from `lxc-container:` to
`lxc_container:`. All of the entry points have been changed in
support of the new upstream module and the carried `lxc-container`
module has been removed.
