Fix Integration Proxy for cross region integrations

[sentaur-athena]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

Today our integration proxy doesn't work when two orgs in different regions use the same integration. Example is Sentry us org and Sentry de org using the same slack workspace.

The logic fetches all the orgs and basically return the one in DE all the time. To fix we need to provide more context to integration proxy to be able to make this decision.

Expected Result

Integration proxy proxies to the right org if the same integration is connected to 2 orgs.

Actual Result

Integration proxy always proxies to DE if there are 2 regions
