This commit adds a doc for `kg`, the Kilo agent that runs on every node
in the mesh. This includes: the doc itself, files needed for the

If we tag a release for, e.g. 0.1.1, after we've already cut a 0.2.0
tag, then CI would tag the 0.1.1 image as `latest`, which is confusing.
This commit ensures that we only tag the `latest` image when building
from master.

Previously, when `deleteFromIndex` exited early due to an error, nil
rules would be left in the controller's list of rules, which could
provoke a panic on the next reconciliation. This commit ensures that nil
rules are removed before an early exit.

Pod subnet as well as from peers. This means that Pods can access the
Internet and that peers can use the Kilo mesh as a gateway to the
Internet.

This commit better organizes the location of iptables rules. This is
made possible by exposing two new funcs, `NewRule` and `NewChain`.
