[FEATURE] Terraform Provider for OpenAI

[jianyuan]

Is your feature request related to a problem? Please describe.
Managing API keys and configuring OpenAI projects manually can be tedious and error-prone, especially for teams managing multiple projects and environments. It becomes challenging to ensure consistency and security across configurations when done manually.

Describe the solution you'd like
I have developed an OpenAI Terraform Provider which simplifies the management of OpenAI projects by allowing users to:

• Automate project configurations through Terraform scripts.
• Generate and manage API keys programmatically.
• Ensure configurations are version-controlled and reproducible.

This solution integrates seamlessly into existing Infrastructure as Code (IaC) workflows, enabling teams to manage OpenAI resources alongside their infrastructure efficiently.

Additional context
I would be delighted to contribute a detailed article or guide on using this provider, showcasing its features, benefits, and use cases. Please let me know if this would be a welcome contribution!
