Integtests support for multiple plugins

[setiah]

Currently, the integ test instrumentation works fine when running for one component and all possible configurations but it fails when multiple components are tested as part of the same workflow. The instrumentation logic needs to be fixed to handle that.

• Rework instrumentation logic
• Fix alerting, reports-scheduler, notebooks integ test instrumentation

Steps to reproduce -

1. Run integration tests on main branch
   bash test.sh integ-test --test-run-id <execution-id> --s3-bucket <bucket_name> --opensearch-version <version> --build-id <id> --architecture <arch>
