Separate setup code in storage proxy

[HyeockJinKim]

User story

• As a developer, when I am working on the storage proxy, I want to separate the setup code using aiohttp into the setup package so that I can maintain a cleaner codebase.
• As a developer, when I implement the setup package, I want it to have the same interface for setup so that it can be easily integrated.
• As a developer, when I need to verify the setup, I want to develop a CLI so that I can confirm the setup process works correctly.
• As a developer, when I have the setup values, I want to replace the existing code to run the server so that the application functions as intended.

Context

The issue involves separating the setup code currently in the storage proxy into a dedicated setup package. This will help streamline the code and ensure that the setup process can be verified through a command-line interface (CLI).

Acceptance criteria

• The setup code in the storage proxy must be separated and moved to the setup package.
• The setup package should maintain the same interface for setup operations.
• A CLI must be developed to verify the setup process.
• The existing code must be replaced to allow the server to run using the setup values received.
