[Feature request] Check that hub_hostaddress is reachable every X hours/days

[Ch0kehold]

I am not entirely up to par in lua scripting, so I would like to request a feature to have the hub bot actively ping the address set in hub_hostaddress every X hours or possibly days. If the address is reachable, it simply breaks and does nothing more, while if not reachable it could send a message to bot_opchat (if bot_opchat_activate is true of course) or otherwise post a message in main or something to that effect, to get the attention of someone so the issue can be resolved.

The reasoning behind this is that renewing possibly expiring DNS redirect services (such as, but not limited to, free noip/ddns addresses) can sometimes be overlooked by owners,
This feature would serve as a reminder of sorts in the event that such a service expires, and also help catch DNS issues early in other cases.

That sounds like a good idea.

If you don't want to wait you can registered for a free account on UptimeRobot and it will send a message to an email address or you can use an RSS Feed and monitor the hub when it goes up and down.
