Configure Sentry integration with PagerDuty using API

### Problem Statement I want to configure an existing PagerDuty integration in Sentry to add a new integration key for the service using the REST API. This feature is essential for providing standardized observability workflows, and creating integrations for hundreds of services manually is not viable. ### Solution Brainstorm Support team pointed me to a previous request, which was closed as won't do: [https://github.com/getsentry/sentry/issues/99917](<https://github.com/getsentry/sentry/issues/99917>) I understand the manual step in the UI would be hard to implement in the API as it is. It creates the integration in PagerDuty for me. I wanted to take a different approach, create integration in PD using their API, and then provide the integration key to Sentry. Then there's no need to authenticate with PD on the Sentry side, reducing the complexity. ### Product Area Settings - Integrations We want to define a set of [lightweight metrics](<https://docs.sentry.io/product/explore/metrics/>) that SDKs can automatically collect for e.g. framework, language or platform, focusing only on signals that **do NOT overlap with Tracing**. Ideally these metrics should give a quick sense of app or runtime health, … while deeper investigation will still rely on traces or profiles.<br><br>Examples**:** * Node.js runtime metrics (e.g., event loop delay, heap usage) * Prisma-related metrics in Next.js * Mobile CPU / memory usage to help surface potential ANRs or app hangs --- **Candidate Metrics (add more below)** * … *(please also add ideas, questions or examples in comments)*
