close CLOUD-217

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - Introduced a dedicated test job for Elasticsearch, running only Elasticsearch-specific tests during CI.
- **Chores**
  - Enhanced server test workflows with explicit setup steps and automated coverage uploads.
  - Improved test suite structure for Elasticsearch provider to enable conditional and asynchronous test execution based on environment variables.
