Allow to disable default gw feature
- Default gateway is a good feature for having host discovery, and
consequently hosts' pings, work out of the box.
But in real scenarios a controlled network node may be connected to a
legacy switch's trunk port which exposes thousand of hosts which ARP
packets would easily stress controller functionality.
Even though today this can be prevented by configuring a more
specific subnet gateway, the issue is very much possible at first
controller boot, and can always re-occur during subnet config manipulation
if at any point of time we have no user configured subnet gateways.
- This patch provides a way to disable he default gw feature by mean of
a property in config.ini. Property addition is not included, current
behavior is unchanged.
