[v0.13.x] Fix formatting with cluster-autoscaler

[dominicgunn]

Changes

• Fixes the formatting used by the Go Templates when creating the option set for cluster-autoscaler, with the current setup the formatting will indent the text too far as shown below.

- --expander=least-waste
              - --a=b
              - --c=d

Bumping them a little to the right fixes the formatting.

Resolves #1653
