Switch off leader election for scheduler and kube/cloud controller

**What this PR does / why we need it**:

We now have leader election on by default, for a single node
local-up-cluster, this is not needed. Let's switch it off

This will reduce the flakiness and timeouts we see in the local e2e CI jobs.
