Add tooling support to use Kibana dashboards interactively

[danielmitterdorfer]

The Kibana queries that are being issued to build the Kibana dashboards are quite complex. To help maintaining them better, it would be great if we had a script that would populate some data to a local Elasticsearch instance and import the dashboards.

Implementation note: The building blocks are already there - there is a script to import the data and we can run a regular challenge with proper track parameters to ingest a smaller data set.

It would also be useful if a human user could interact with these dashboards with their browser during a challenge to get a better feel for what a Kibana user would experience under load.
