Code Issues Proposed changes

Send gratutious ARPs on ip monitor event also 

This commit sends gratuitious ARP requests in case
ip_monitor returns zero exit code. This will allow
for periodical updates of neighbours in case our IP
is OK and neighbour did not receive arps of the node
after ip was initially started.
