If ProvisionGuestProxyAgent is true, query azure-proxy-agent status, waiting up to 120 seconds for the proxy to negotiate with Wireserver and configure an eBPF proxy. Once azure-proxy-agent is ready, it will exit with code 0 and cloud-init can then expect to be able to communicate with these services. Fail deployment if azure-proxy-agent is not found or otherwise returns an error.

In certain supported ubuntu images, static udev rules or netplan yaml config is delivered in the base ubuntu image to support dhcp on any additional interfaces which get attached by a customer at some point after initial boot. Since the Azure datasource can now regenerate network configuration as metadata reports these new devices, we no longer want the udev rules or netplan's 90-hotplug-azure.yaml to configure networking on eth1 or greater as it might collide with cloud-init's configuration. Remove the any existing extended network scripts if the datasource is enabled to write network per-boot.
