Add an option to deploy Hyperswitch in AWS Free Tier using minimum infra requirements

[shakthi-22]

Currently, the CDK script provides a scalable setup using AWS EKS but incurs charges on a daily basis. This may not be very suitable for users who simply want to try out the CDK script on their own AWS account and experience what Hyperswitch has to offer. Therefore, the goal is to offer an option for users to install Hyperswitch using minimal resources that fall under the AWS Free Tier. This way, they can deploy and try Hyperswitch for free.

This deployment will only be aimed at users who want to quickly try Hyperswitch on their own cloud without incurring any cost.
This will be not be a production ready and scalable setup
