Load test data into postgres

Do this for individuals and datasets models. Can use test data from this repo: https://github.com/EGA-archive/beacon2-ri-api/tree/master/deploy/data

Need to:

• transform json to csv
• create a script that would load the csv into postgres

We will need posgtes to have the models for individuals and datasets tables before these can be imported in

ended up generating test data of our own, for a limited model of individuals and datsets to ensure we can easily demo, will not use the Json files from ega after all.

@sergiygetlin is looking into how easy it will be to load the manually generated test data into the db via liquidbase (so we dont have to do it manually or with a script, we just get it with the localhost postgres db)
