Deprecate --format for podman top

Issue #169 describes a common failure when running podman top where
if the commands inside the container container a space in them, podman
will panic.  This was occuring because we take the output from ps and
attempt to format it nicely for output and things like JSON.  Given that
this cannot be predicted or dealt with programatically, the decision was
made to deprecate the format switch and simply output what ps provides
us.

Migrated top integration tests to ginkgo.
