Add local EBT shipper

[afharo]

Summary

This PR adds an example plugin that registers an EBT shipper that writes all the events to the local ES.

It's intended for development purposes. With this plugin devs can look realtime at their local discover all the events their local Kibana is generating.

Just add the dataviews ebt-kibana-server/ebt-kibana-browser to start exploring.

@TinaHeiligers thanks for the reviews! I revisited the comments inside the required-but-left-empty methods to be less "I don't care" and provide better reasoning for not implementing anything inside those methods. Please, let me know what you think.

LGTM

This was in my notif list, so I was just passing by, but there's no update in one month so I will ask: should that be merged?

IIRC, I didn't merge it because we wanted to discuss further if we wanted this to be either a disabled-by-default plugin (instead of an example plugin) or a disabled-by-default feature inside the telemetry plugin. This way it can be reused in more scenarios (yarn start --serverless=es --run-examples doesn't run the examples, so the local EBT client cannot work when developing for serverless).

Happy to continue the discussion and adapt the PR.

I've recently seen a few "complains" about EBT not being testable locally. So I decided to push this PR forward.
