Add a daemon that will allow us to test the zapi as well as test route install/removal times from the kernel. The current commands are: install route <starting ip address> nexthop <nexthop> (1-1000000) This command starts installing at <starting ip address>/32 (1-100000) routes that it auto-increments by 1 Installation start time is noted in the log and finish time is noted as well. remove routes <starting ip address> (1-1000000) This command removes routes at <starting ip address>/32 and removes (1-100000) routes created by the install route command. This code can be considered experimental and *is not* something that should be run in a production environment. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
