display logs for multiple containers at the same time

add the ability for users to specify more than one container at a time
while using podman logs.  If more than one container is being displayed,
podman will also prepend a shortened container id of the container on
the log line.

also, enabled the podman-remote logs command during the refactoring of
the above ability.

fixes issue #2219
