Broken Elasticsearch Data Filtering Example

[David]

Whilst trying to prove out OPA with Elasticsearch for my team I ran into several issues with the Elasticsearch data filtering example. I personally have not been able to successfully get past step 2 in the README.

Asking for help to ensure the example can run against newer versions of Elasticsearch and also support communicating to containerized Elasticsearch.

Hi David! 👋 And thanks for reporting this. From what I can see, it's been 4 years since someone actively worked on this, so things have likely changed in Elastic-land since then. Should probably not be too much work to fix if someone wants to pick it up. I'll mark this as a good-first-issue, hoping someone steps up to the challenge :)

Hey @daurrutia,
Please try building and running my fixed version.

@anderseknert would appreciate your review on my PR 😃
