Update the admin username and password of the VMs in a cluster

Each node type in a Service Fabric cluster is a virtual machine scale set. This sample script updates the admin username and password for the cluster virtual machines in a specific node type. Add the VMAccessAgent extension to the scale set, because the admin password is not a modifiable scale set property. The username and password changes apply to all nodes in the scale set. Customize the parameters as needed.
