feat: Add new Grafana dashboards: Aggregated Reports, Project Insights, and User Insights

[davidpepm]

Description

This pull request adds three new Grafana dashboards to the AI DIAL Realtime Analytics project as part of the requirements outlined in [Issue #62](#62).

The new dashboards are as follows:

1. DIAL Analytics Aggregated Report: Focuses on aggregated metrics, providing insights derived from pre-aggregated data for performance optimization.
2. DIAL Project Insights: Offers detailed analytics at the project level, enabling better monitoring and understanding of project-specific metrics.
3. DIAL User Insights: Provides user-level analytics to track and analyze individual user behavior and contributions.

Dependencies

This PR is dependent on the following pull request in the InfluxData Helm Charts repository:

• [PR #692](Feature/691 Add Bucket and Task Creation Support to Helm Chart influxdata/helm-charts#692): Adds the required buckets and tasks to support the new Grafana dashboards.
  This pull request must be merged before this one can be fully functional.

Changes in this PR

1. Added three new dashboard JSON files under the Grafana Dashboards directory:
   • DIAL Analytics Agg.json
   • DIAL Project Insights.json
   • DIAL User Insights.json
2. Updated the project documentation (README.md) to reflect the addition of these dashboards.

Testing

Please ensure the following:

• All pre-requisite dependencies from the InfluxDB setup are correctly deployed and functional.
• Grafana is configured to load these new dashboards and displays the expected data as visualized.

Issue Reference

Closes [Issue #62](#62) once merged.

Notes

These dashboards rely on aggregated data for improved performance. Ensure the required changes in the InfluxDB Helm Chart repository have been deployed and tested before integrating this PR.
