Description

Goal

The goal of this PR is to fix an issue in AAQ prod and testing where it fails sometimes but sometimes work

Changes

Here are the changes made to fix

• Increase time outs
• Create an sqlalchemy inside therefresh_insightsfunction instead of using the one from request. This is because that asession instance is supposed to close after the function finish executing.
• Added TOKENIZERS_PARALLELISM environment variable to avoid warning about parallelism issue.

Future Tasks (optional)

• The bokeh plot still seems to be buggy. Needs to be fixed

How has this been tested?

Can test by adding the dummy data using add_dummy_data.py. Then run discovey (better results when running two at the same time).
