sharpd: Add Super Happy Advanced Routing Protocol

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.
