Openhab cloud connection stops working, does not try to reconnect

@seanch ~~try the version in https://github.com/openhab/openhab-addons/pull/12430~~

UPDATE: I have now published the addon in the marketplace, to allow even more easy installation (and further updates)

You can find them from the MainUI marketplace view with “cloud connector troubleshooting version” keyword. Direct links for marketplace forum posts: openHAB 3.2.0 version and openHAB 3.3.0-SNAPSHOT version.
