az aks bastion fails when bastion is on a different Subscription

[AndreasMWalter]

Describe the bug

 az aks bastion --name aks-cluster --resource-group aks-resource-group --subscription <aks subscription id> --bastion /subscriptions/<hub subscription id>/resourceGroups/bastion-resource-group/pro
viders/Microsoft.Network/bastionHosts/bastion-name --verbose

Results in:

creating temporary directory: /tmp/teynde
Merged "aks-cluster" as current context in /tmp/teynde/.kube/config
Converted kubeconfig to use Azure CLI authentication.
Creating bastion tunnel with command: 'az network bastion tunnel --resource-group bastion-resource-group --name bastion-name --port 43157 --target-resource-id /subscriptions/<aks subscription id>/resourcegroups/aks-resource-group/providers/Microsoft.ContainerService/managedClusters/aks-cluster --resource-port 443 --subscription <aks subscription id>'

It points the subcommand to an incorrect subscription_id it should receive the subscription_id from the resource_id of the bastion but points it to the subscription id of the AKS cluster

Related command

az aks bastion --name aks-cluster --resource-group aks-resource-group --subscription --bastion /subscriptions//resourceGroups/bastion-resource-group/pro
viders/Microsoft.Network/bastionHosts/bastion-name --verbose

Errors

Bastion tunnel exited with code 3

Issue script & Debug output

N/A

Expected behavior

Properly pass the correct subscription_ids to the subcommand
