[tool] Testing pytest on connectors

[aHenryJard]

Proposed changes

• Add test-requirements.txt file for folders which have tests
• Add a shell script file which look into folder to find test-requirements file and install necessary dependencies for running the tests
• Complete config.yml for CircleCI
• Only 4 connectors use Poetry package manager, in order to be aligned with all other connectors, it will be replaced with requirements.txt file. Concerning connectors:
• External import connector: ironnet and urlscan
• Internal enrichment connector: shodan-internetdb
• Stream connector: elastic

Further comments

For connectors that already have tests folder:

• Install testing libraries and requirements:

And display test part for checks:
