Add Health Check Endpoint for Node Types in Handlers and Routes

[Sophie-Ag00001]

PR Description: Implement Health Check Endpoint for Node Types

Summary of Changes

This pull request introduces a health check endpoint across multiple node types within the network. The following changes have been made:

1. Implemented the health_check function in handlers.rs.
2. Updated routes.rs to add the .or(...) block for the health_check handler in the routing logic for each node type: User, Storage, Mempool, Miner, and Miner+User.

Motivation

The addition of a health check endpoint allows for better monitoring and stability of the network. It provides developers and operators insight into the operational status of various node types and improves overall system reliability.

Relevant Context

Health checks are vital in distributed systems to ensure that each component is functioning correctly. Integrating this endpoint across all node types enables centralized health monitoring and aids in troubleshooting potential issues.

Testing Instructions

To verify the implementation:

1. Start the server.

2. Send GET requests to the /health endpoint for each node type:

   • User: /health/user
   • Storage: /health/storage
   • Mempool: /health/mempool
   • Miner: /health/miner
   • Miner+User: /health/miner_user

3. Ensure that the expected health check response is received from each endpoint.

Known Issues/Limitations

• No known issues at this time. Please report any anomalies encountered during testing for further investigation.

We appreciate any feedback on this implementation to enhance the health monitoring capabilities of our network. Thank you!
