Add Support For Batch Commands

[ezrasingh]

Is your feature request related to a problem? Please describe.

Executing multiple commands individually is time-consuming and inefficient, especially for large datasets or frequent operations.

Describe the solution you'd like

Add support for batch commands to allow grouping and executing multiple commands in a single operation, significantly improving efficiency.

Describe alternatives you've considered

A scriptable interface for manual batch operations, but built-in support would be more user-friendly and integrated.

Additional context

Features could include:

• A batch API for defining and executing multiple commands.
• Support for searching across multiple geoshards in a single batch operation.
• Enhanced error handling for batch commands.
• Status reporting for execution results and errors.
