webhooks.hpa.enabled	bool	false	Whether horizontal pod autoscaler (HPA) is enabled for the webhooks.
webhooks.hpa.maxReplicas	int	nil	The upper limit for the number of pods that can be set by the autoscaler. Cannot be smaller than minReplicas. Required when enabled is true.
webhooks.hpa.metrics	list	[]	The specifications used to calculate the desired replica count (the maximum replica count across all metrics will be used). If not set, the default metric will be set to 80% average CPU utilization. Only applicable when apiVersion is autoscaling/v2.
webhooks.hpa.minReplicas	int	1	The lower limit for the number of replicas to which the autoscaler can scale down.
webhooks.hpa.targetCPUUtilizationPercentage	int	nil	The target average CPU utilization (represented as a percentage of requested CPU) over all the pods. If not specified, the default autoscaling policy will be used. Only applicable when apiVersion is autoscaling/v1.
