Add validation to ping the default gateway(s)

This patch adds a new function that runs on all nodes so that
all default gateways are ping tested early on during the
installation process (before any puppet is executed)

Note: this change depends on the static control plane network IPs
because some distros allow/create multiple default routes without
this patch (see depends-on below).
