Subject: 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
