[Feature Request] Add Version Tracking for Search Pipelines

[mingshl]

Is your feature request related to a problem? Please describe

Description:

Currently, when a user updates a search pipeline, there's no way to track or view the previous versions of that pipeline. This makes it difficult to understand the evolution of a pipeline over time or to revert to a previous version if needed.

Describe the solution you'd like

Feature Request:
Implement a version tracking system for search pipelines that allows users to:

1. View the history of changes made to a search pipeline
2. Compare different versions of a search pipeline
3. Revert to a previous version of a search pipeline if needed

Use Case:

When using a search pipeline like:
GET /my_index/_search?search_pipeline=my_pipeline

Users should be able to:

• See when and how the pipeline was last modified
• Access a list of previous versions
• View the differences between versions
• Easily roll back to a previous version if the current one has issues

Potential Implementation:

• Store each version of a search pipeline with a timestamp and version number
• Provide a new API endpoint to retrieve version history
• Add a UI component in the OpenSearch Dashboards to visualize and manage pipeline versions

Benefits:

• Improved tracking and auditing of search pipeline changes
• Easier troubleshooting and debugging of search behavior
• Ability to revert problematic changes quickly
• Better collaboration among team members working on the same pipelines

Additional Considerations:

• Consider adding user information to track who made each change
• Implement a retention policy for old versions to manage storage
• Allow users to add comments or descriptions to each version
