tun_disabled: reply to ICMP Echo Request (#342)

Browse Source 
This change allows a server running with `tun.disabled: true` (usually
a lighthouse) to still reply to ICMP EchoRequest packets. This allows
you to "ping" the lighthouse Nebula IP as a quick check to make sure the
tunnel is up, even when running with tun.disabled.

This is still gated by allowing `icmp` packets in the inbound firewall
rules.
