What happened:
Not possible to run less than 3 instances of the query pods when using the helm chart without also configuring the horizontalPodAutoScaler.

What you expected to happen:
That setting query.replicas to 1 was respected.

How to reproduce it (as minimally and precisely as possible):
Set query.replicas to 1 when using the helm chart.

Open Match Release Version:
1.8.0

The problem is that the values.yaml have minReplicas set to 3 as a default values for the horizontalPodAutoScaler:
query: minReplicas: 3 maxReplicas: 10 targetCPUUtilizationPercentage: 80
