Seperate tests.json files to smaller files

[GalRogozinski]

Description

We want each test to be represented by his own file.
This is so that we can track changes with more ease.

Requirements

[ ] - large tests.json file should be still generated but taken out of the repo
[ ] - instead commit to the repo the small tests.json files
[ ] - stop compressing the large json file (because git already does compression so it is redundant)
