Azure Kubernetes Service Start Cluster

arazzo: 1.0.1
info:
  title: Azure Kubernetes Service Start Cluster
  summary: Start a stopped AKS cluster, poll until provisioned, then fetch user credentials.
  description: >-
    Starts a previously stopped managed cluster, polls the cluster Get endpoint
    until provisioningState reports Succeeded (looping while it is still
    Starting), and then lists the cluster user credentials so a kubeconfig is
    ready as soon as the cluster is back online. Every step inlines its request
    so the flow can be read and executed without opening the underlying OpenAPI
    description.

    Calls ManagedClusters_Start, polls ManagedClusters_Get until
    provisioningState is Succeeded, then calls
    ManagedClusters_ListClusterUserCredentials.
