Set Kubernetes cluster nodepool to minimum 0 nodes

[OscartGiles]

Feature overview

It's now possible to have zero nodes in a node pool (as long as it isn't the main node pool). However, terraform hasn't been updated yet.

@OscartGiles manually set the node pool to autoscale to zero.

Once this is available on terraform we need to update this code:

clean-air-infrastructure/terraform/data_collection/kubernetes/main.tf

Lines 64 to 74 in 2134eed

	resource "azurerm_kubernetes_cluster_node_pool" "jamcam_pool" {
	name = "jamcam"
	kubernetes_cluster_id = azurerm_kubernetes_cluster.this.id
	vm_size = "Standard_NC24"
	enable_auto_scaling = true
	max_count = 4
	min_count = 1
	node_count = 1
	os_disk_size_gb = 100
	node_taints = ["group=gpu:NoSchedule"]
	}
