Big NodeJS-Reports

[Reamer]

Describe the bug
HTML-Reports get really huge (> 60MB). I faced this issue with a nodejs report and mysql. MySQL isn't supported by sonarqube. Maybe a change to postgres solved this issue.

To Reproduce

1. Create a nodejs report

Current behavior
Database is bloated with reports.

Expected behavior
We doesn't want to change the original report, maybe it's possible to compress the report and serve as a download.
