Code Issues Proposed changes

Add ping test for all networks gateway IPs 

Add ping test for gateway IPs on all networks, to ensure
all gateways are reachable.

The releated Bugzilla reports an issue where some network
fabrics fail when using the current node ping test, which
pings the first node in each role. The fabric simply does
not forward traffic before the gateway has been pinged.

One can argue that the fabric in question is broken. However,
with the current implementation the first node in each role
actually ping tests only against it's own address? So adding
the test to ping the gateway addresses improves the validation
in general.
