Consul for Raspberry Pi is Alive

This version is forked from and runs on the Raspberry Pi. Thanks to Jeff Lindsay for all his hard work. I am merely standing on the shoulders of giants. This initial version is a bit largish — ~500Mb; I think it’s mostly due to needing a go build environment. I think I can use …
