stats: add a interval parameter to cli and api stream mode
podman stats polled by default in a 1 sec period. This can put quite some load on a machine if you run many containers. The default value is now 5 seconds. You can change this interval with a new, optional, --interval, -i cli flag. The api request got also a interval query parameter for the same purpose. Additionally a unused const was removed. Api and cli will fail the request if a 0 or negative value is passed in. Signed-off-by: Thomas Weber <towe75@googlemail.com>
