Stage3 Image Library
This represents the stage3 implementation for the image library. At this point, we are moving the image-centric functions to pkg/image including migration of args and object-oriented references. This is a not a one-for-one migration of funcs and some funcs will need to continue to reside in runtime_img as they are overly specific to libpod and probably not useful to others. Signed-off-by: baude <bbaude@redhat.com> Closes: #484 Approved by: baude
