The `keepalive` is always set to `KEEP_ALIVE_SEC` and cannot be overridden by the user. This fix uses the user-provided `keepalive` from `kwargs` and defaults to `KEEP_ALIVE_SEC` if there is None.
This fixes#28
Fix KEEP_ALIVE_SEC to be 60 seconds instead of the current value of 3600 which is in fact an hour.
This fixes#25 which is an issue because the broker disconnects after 300 seconds with no ping.
