Alpine Support

I'm trying to set up nanobox to deploy from my C.I. environment, which uses alpine as a base image.

I have C.I. logs here

  function print_system_info() {
    uname -a
    cat /etc/*-release
    echo "systemd: $(which systemd)"
    echo "upstart: $(which upstart)"
    echo "systemctl: $(which systemctl)"
    echo "initctl: $(which initctl)"

  }

$ print_system_info
Linux runner-72989761-project-3569426-concurrent-0 4.13.5-coreos-r2 #1 SMP Thu Oct 12 03:21:09 UTC 2017 x86_64 Linux
3.7.0
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.7.0
PRETTY_NAME="Alpine Linux v3.7"
HOME_URL="http://alpinelinux.org"
BUG_REPORT_URL="http://bugs.alpinelinux.org"
systemd: 
upstart: 
systemctl: 
initctl 

I'm checking for the (at the time of writing this), the 4 scheduling tools that nanobox supports on linux. None of them exist.

Alpine uses this: https://wiki.alpinelinux.org/wiki/Alpine_Linux_Init_System

Alpine is growing in popularity where size/network usage is a concern, so I think this would be a good addition to support. :-)
