KMS Testing: Dedicated server setup #1047

Describe the current behavior
Currently, we have not dedicated server where we can test the KMS-related testing is performed using the existing staging infrastructure, which is not ideal for isolated testing. There is no dedicated development server or supporting resources for validating KMS changes independently.

Describe the enhancement you'd like
Set up a dedicated development server for KMS testing within the Kaapi Staging VPC with the following configuration:

• Provision a new development server for KMS testing.
• Allow the server to access the existing Staging RDS instance.
• Create a new database inside the staging RDS specifically for KMS testing.
• Create a dedicated RabbitMQ virtual host (vhost) for the KMS environment.
• Create a dedicated Redis database for the KMS environment.

This will provide an isolated environment while still leveraging the existing staging infrastructure.
