Fix tolerations parsing

[GuyCarmy]

The way the chart parse tolerations doesn't match the example given in your values file.

This is an easy fix as suggested in this PR.
Also you might have the same issue in other places but I didn't check or need them.

before the fix:

      tolerations:
        - effect: NoSchedule
key: kubernetes.azure.com/scalesetpriority
operator: Equal
value: spot

after the fix

      tolerations:
        - effect: NoSchedule
          key: kubernetes.azure.com/scalesetpriority
          operator: Equal
          value: spot

*also validated with 2 tolerations and with zero tolerations

      tolerations:
        - effect: NoSchedule
          key: kubernetes.azure.com/scalesetpriority
          operator: Equal
          value: spot
        - effect: NoSchedule
          key: test
          operator: Equal
          value: spot
