Create a two-pi-plus-dev setup for durio.

1. Three IPs are hard coded, one for the dev machine and two for Pis.
2. The two Pis must be connected to the same network as the dev
machine.
3. A script (build.sh) is added to cross build to an ARM binary.
4. A script (curl.sh) is added to test the services.
