Throw Error in Maxi Alerts when Gauge adder Fails

[Xeonus]

We had now multiple instances where the gauge adder failed and no error log was forwarded to our monitoring. We also didn't receive alerting via email.

Let's fix this.

We have a monitoring config in place which needs to be reviewed

[Tritium-VLK]

Any time any OZ job fails we should get an alert and someone should look into it.

We agreed to setup a new alerts channel for things that need response and aren't just info.

Channel is setup, invited both @Xeonus and @Hyferion the same bots we are using in the current (info) channel are also there.
