[AGPT-698] Update cli commands and add groq integration

[Swiftyos]

• Allows configuration of codex-url so we can use resume on gcp envs
• Adds a quick an easy way to switch to groq and override chat model and max tokens
• Added rate limiting based on requests per minute (10_000) and number of concurrent requests (1_000) defaulted to our openai limits

Questions to better understand the PR:

1. Was the removal of port configuration in CLI commands replaced entirely by the base URL configuration, or is there another mechanism to specify the port now?
2. Does the GROQ integration default to using the "llama3-70b-8192" model only when no other model is specified, or is it a fixed setting?
3. How are the new rate limits configured in the OpenAIChatClient class intended to interact with the existing system's throughput and performance?

Please respond to the questions above in the following format:

1. Yes we now use url only as that includes the port
2. We use llama 3 when no model is specified for groq
3. Its meant to limit the existing system, though defaults match our limits with openai
