Add Resources for Hosting Application Layer of LLM App

[kkiani]

Description:

This issue suggests adding resources to support the application layer of the LLM app, specifically for hosting the prompt engineering code. The implementation will include creating an AWS Lambda function, providing a mechanism for uploading the application code to the Lambda, and handling the installation of necessary dependencies for the code.

Tasks:

• Define an AWS Lambda function.
• Implement code deployment (e.g., S3 or direct upload) to the Lambda function.
• Figure out how to package and install the required dependencies (e.g., using Lambda layers or bundling with the deployment package).
