[Integration Platform] Deactivate Integrations with Failing Webhook Requests

### Problem Statement

Integrators want to limit the amount of traffic from Sentry to their webhook endpoint for installations associated with inactivate accounts in their 3rd party service

### Solution Brainstorm

Sentry doesn't currently deactivate integrations where the webhook is failing consistently automatically.
If we did make this change it would help integrators deal with unwanted ingress to their webhook endpoint more easily.

### Product Area

Settings - Developer Settings

Start with the Problem Statement and Solution Brainstorm, then inspect the Settings - Developer Settings integration area to identify the webhook request and integration lifecycle entry points. Define how consistently failing requests are detected and how deactivation is surfaced; done means integrations for inactive third-party accounts no longer generate unwanted webhook traffic.
