Add a new function for converting a CreateConfig
Right now, there are two major API calls necessary to turn a filled-in CreateConfig into the options and OCI spec necessary to make a libpod Container. I'm intending on refactoring both of these extensively to unify a few things, so make a common frontend to both that will prevent API changes from leaking out of the package.
