    Removed default value for 'Physical Network'

    When creating a network there is currently a default value of 'default'
    which causes the network creation to fail. It is nonsensical to have
    a default value here as it will change depending on the provider
    network type and needs to be set according to custom settings if the
    user is not creating a simple local network which then does not require
    the physical network value at all.
