feat(tool/sendsms): a CLI to send SMS

This is a new tool to send SMS via Twilio's API. For now it supports a
single subcommand: reboot. Using that subcommand, a SMS will be send
with the name of the host and the IP address for the defined network
interface. This is useful to be notified when one of my machine reboot,
and what's the IP for the main interface (this is useful since my ISP
does not provide a static IP).
