feat: add startup taint removal feature

This PR is for solving the race condition between CSI driver initialization and disk volume scheduling, you could find details here: kubernetes/kubernetes#95911

user should add taint(disk.csi.azure.com/agent-not-ready:NoExecute) to node pool before CSI driver starts up

• testing example

kubectl taint nodes aks-user-34333166-vmss000000 disk.csi.azure.com/agent-not-ready:NoExecute

• tested upgrade from previous version

Special notes for your reviewer:
There is a race condition between CSI driver initialization and kube-scheduler, we have added a taint removal feature (when CSI driver is started up) from aks 1.30, so cx could mitigate this issue, add taint disk.csi.azure.com/agent-not-ready:NoExecute in node pool creation and then after CSI driver is started, the taint would be removed by the CSI driver, that won’t be any race condition between CSI driver initialization and kube-scheduler any more.

Use node taints in an Azure Kubernetes Service (AKS) cluster - Azure Kubernetes Service | Microsoft Learn
az aks nodepool add
--resource-group $RESOURCE_GROUP_NAME
--cluster-name $CLUSTER_NAME
--name $NODE_POOL_NAME
--node-count 1
--node-taints "disk.csi.azure.com/agent-not-ready:NoExecute"
--no-wait
