Replace Get_orgs

[edujosemena]

Fixes #639

🗣 Description

For preventing sql injection errors the team is focusing on creating more API endpoints to interact with instead of using direct API calls. To get this going we need to modify the get_orgs function in db_query to get the data from the api endpoint in crossfeed rather than directly use TSQL.

Implementation notes

• Replace get_orgs()
• Assure the same data is received with using the api rather than TSQL
• Get URL and API_KEY in database.ini file

🧪 Testing

API endpoint is successfully called using the requests library
