[Review] carefully: salt.cloud.lxc & lxc revamp for unification

salt.cloud is adaption to the lxc.runner/module.init interfaces, not the contrary, amongst a lot of other fixes and features (like vt support)
there were a lot of inter dependencies on the lxc modules functions and this then resolve the burden of declaring the functions in the right order, (if i remember well, there was even a cycle)
