Enable custom options for addons

- Add an options parameter to the start() event. This is to be used by addons
on startup to add custom options.
- Add a running() event that is called once the proxy is up and running.
- With the new paradigm we can't log during master __init__, so add a tiny
termstatus addon to print proxy status to terminal once we're running.
