api: utils: add an `IsLibpodRequest` handler
Add a hanlder to figure out if the specified http request came through a libpod endpoint. A first user is the top endpoint which has a different default value for `ps_args` depending if the request came through the docker or libpod endpoint. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
