Collected and added advisories from zerodayinitiative

Fix #1471

Changes made :

1. Added ZDI importer to import advisories (fetching, parsing, importing)

2. Added test file for the importer

3. Added Test data files

@pombredanne I have added the pipeline to import the advisories and If you have any suggestions please let me know I will make the changes required.

@pombredanne I have already added pipeline_id = "zdi_importer" but still I am getting the error when I test the changes locally.

Can you please suggest what should I do in this case.

Learn to code.

This is not actionable. Please take the time to learn how to code and stop submitting code that does not run and is AI-generated, wasting precious review time from the maintainers.
If you are able to submit code that is minimally tested and does run and is not AI generated, come back, but only then.
I am going to close all your other PRs for the same reason
