    automation: qemu-smoke-arm64: Run ping test over a pv network interface
    
    This patch modified the test in the following way
    - Dom0 is booted with an alpine linux rootfs with the xen tools.
    - Once Dom0 is booted, it starts xenstored, calls init-dom0less to setup
    the xenstore interface for the dom0less Dom1, setups the bridged network
    and attaches a pv network interface to Dom1.
    - In the meantime, Dom1 in its init script tries to assign an ip to eth0
    and ping Dom0,
    - If Dom1 manages to ping Dom0, it prints 'passed'.
