Handle lost connection to telegram servers gracefully

[luckydonald]

Currently, if telegram isn't working, requests are simply left open, stalling forever.

That's not great as that means basically DDoS potential.

To Reproduce:

1. Lauch bot api
2. Disconnect Wifi or whatever
3. Send a request to the Bot API.
4. ????
5. Boom

So I think it should just return an error right away.
Just like the Internal Server Error: restart one.

@luckydonald I don't get it

It should work with the next update, I'm closing this issue. Reopen it if the problem exists also in the next update.

[luckydonald]

Any concrete commit fixing this?

[cavallium]

Is still not working with the current release?

[luckydonald]

No idea, didn't test yet.
I was rather curious by what it could be fixed now.

Like, did a upstream merge change that, or did one of you lovely people fix it?
