Add CPU Pod Creation Support in Python SDK

Add Pod Creation Support in Python SDK

Description

This PR introduces a basic implementation for creating pods using the Python SDK. Previously, there was no direct support for this, as noted in issue #314. I integrated a minimal version of pod creation and added a unit test to validate its functionality.

Changes Introduced

• Implemented pod creation method in the SDK.
• Added a unit test to verify pod creation.
• Updated the README with instructions on how to create a pod from Python.

Testing

I tested the implementation with the following example:

import runpod

print("Creating CPU pod...")
pod = runpod.create_pod(
    name="test-cpu-pod",
    instance_id="cpu3c-2-4",
    template_id="runpod-ubuntu",
)
print(f"CPU Pod created with ID: {pod['id']}")

The output confirmed successful pod creation:

Creating CPU pod...
CPU Pod created with ID: <POD_ID>

Next Steps

• Review the implementation to ensure it aligns with RunPod's best practices.
