RFE: Specify an existing resource group for the node Resource Group

[ezYakaEagle442]

What happened: https://docs.microsoft.com/en-us/azure/aks/faq#can-i-provide-my-own-name-for-the-aks-node-resource-group As you work with the node resource group, keep in mind that you cannot: • Specify an existing resource group for the node resource group. • Specify a different subscription for the node resource group. • Change the node resource group name after the cluster has been created. • Specify names for the managed resources within the node resource group. • Modify or delete Azure-created tags of managed resources within the node resource group. (See additional information in the next section.)

What you expected to happen:

Customer has it own processes, creates first its RG and need to specify its name at AKS creation time.

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version):
• Size of cluster (how many worker nodes are in the cluster?)
• General description of workloads in the cluster (e.g. HTTP microservices, Java app, Ruby on Rails, machine learning, etc.)
• Others:
