Performance enhancement for podman images
Previous code was using slow routines to collect some of the information needed to output images. Specifically size was being calculated instead of using the cached, already known size already available. Also, straight- lined several of the code paths. Overall assessment is that these improvements cut the time for images in half. Signed-off-by: baude <bbaude@redhat.com> Closes: #365 Approved by: mheon
