Traceback on container exit

[peb-adr]

This is basically the same issue as OpenSlides/openslides-media-service#72.

a85e867 Is the commit which introduced it for this service.
The rest of the problem is the same so I'll copy paste it to here.

Traceback (most recent call last):

sys.exit is set as handler for SIGTERM and SIGINT.
However is seems there was a missed detail. The handler will be called with two arguments (source).
@jsangmeister I guess an easy fix would be adding an (anonymus) function that ignores the the args and then calls exit. But I trust you can find the best suitable solution for this ;) .
