Subject: podman pull should always try to pull

In the case where you have an image local, if the the user runs
podman pull, we should always attempt to pull an updated image.

Added a forceRemote bool to New (image) so we can differentiate
between "pull" or run because the actions differ.  Run does not
need to pull the latest -- only run.

Signed-off-by: baude <bbaude@redhat.com>

Closes: #618
