🧠 Background & Motivation

It originally comes from the SI ticket https://rapid7.atlassian.net/browse/SI-32667, I've been able to find something in the docs here https://developer.connectwise.com/Products/ConnectWise_PSA about the different regions for the API communication (but ATM I cannot log in to precisely point out the place about it, because I cannot use the 1pass credentials.

✨ What Changed

• SDK bump
• plugin.spec.yaml alignment with the current approach (it was updated in 2022, last time)
• Regions support (enum) for the connection schema and handling it in the API object

🧪 Testing

• Adjust changes in the current unit tests
• Cannot test it in staging env, because we don't have a working sandbox at the moment
• The custom plugin was tested out on customers environment and we got a response back that everything worked fine
