Custom Aggregated Reports for E2E Tests

We had been having a few conversations around having aggregated custom reports of our E2E Tests (RSpec)

Few Links to Slack Conversations on the same: https://gitlab.slack.com/archives/C3JJET4Q6/p1575332786111200 https://gitlab.slack.com/archives/C3JJET4Q6/p1575993456193400

As a first iteration, I propose the following:

• we spin up a DB Instance in GCP (MySQL or Postgres)
• Come up with a script that would just update the database with the test failures. This script could be run around the same time when we collate the parallel runs and generate the combined_report.html - this is called here

Please check the comments on the details.
