Don't wait for Spot pool nodes

[aermakov-zalando]

Spot nodes can be terminated at any time, so we don't need to wait for replacement node to come up during the upgrade. This also allows CLM to proceed when AWS doesn't have capacity instead of getting stuck forever.

@szuecs I think Travis is having a bad day today.
