FEAT: Resource Utilization Checks before ingestion.

[vkhinvasara]

Resource Utilization Thresholds: Sending 503 response if CPU/Memory thresholds exceed.

Description

This PR enhances our ingestion pipeline by implementing an overload protection mechanism during peak usage. Specifically, when CPU or memory utilization crosses predefined thresholds, the system will proactively reject further ingestion requests with an HTTP 503 (Service Unavailable) status. This prevents uncontrolled resource consumption and cascading failures.

---

File Changes

• resource_check.rs: This is a middleware which checks resource utilization before every ingestion request.
• modal/mod.rs : To wrap the above middleware.
• http/mod.rs: To expose said middleware.

Summary by CodeRabbit

• New Features
  • Introduced resource utilization checks for incoming HTTP requests. Requests are now automatically rejected with a 503 error if system CPU or memory usage exceeds safe thresholds, helping to maintain server stability under high load.

Walkthrough

A new middleware for monitoring system resource utilization has been introduced and integrated into the HTTP server's middleware stack. This middleware checks CPU and memory usage on each request, rejecting requests with a 503 error if usage exceeds set thresholds. Module declarations were updated to include the new functionality.

Changes

File(s)	Change Summary
src/handlers/http/mod.rs	Added public submodule declaration for resource_check.
src/handlers/http/modal/mod.rs	Imported and inserted resource_check middleware into the Actix middleware stack.
src/handlers/http/resource_check.rs	Introduced middleware function to monitor and enforce CPU/memory usage limits per HTTP request.

Poem

A rabbit hops through server land,
Checks the CPU, memory at hand.
If things get hot, requests denied—
With 503, the truth supplied.
But when the coast is clear and bright,
The server runs both fast and light!
