CI: Drop Travis integration or limit Travis notifications to errors only
- We're running our own CI infrastructure since quite some time. IMHO, this works quite well.
- Therefore, I would like to drop Travis, because of two points: Nowadays, it's just unneeded and kind of obsolete, and at the same time, the notifications are just really annoying, IMHO at least, and quite noisy. Edit: This would be the route I would prefer.
- In case dropping Travis is too invasive, I would like to change the Travis settings to be only notified in case of build errors, that is, no notifications should be send if builds are successful.
What do you think?
