add scheduler safeguard

[deer-wmde]

alternative or addition to #916

Did you already try this locally and confirm fewer jobs are fired?

From my rough inspection of how scheduling tasks is supposed to work I think this is unnecessary and I would expect tasks from Kernel.php to only be scheduled by our scheduler pod.

Specifically I am looking at

api/start.sh

Line 26 in e629b07

elif [ "$role" = "scheduler" ]; then

which appears to me to only schedule tasks on the scheduler pod anyway.

Therefore I think we should try #916 first in preference to this
