AICaller not initialized properly with api_key, api_base, and missing max_tokens argument in parse_args_full_repo #318

When running the main_full_repo entry point in the Qodo project, I encountered the following issues:

Arguments not passed to AICaller:
Although the main_full_repo function accepts arguments like --api_key and --api_base, they are not actually passed when initializing the AICaller. This results in the settings being ignored.
I found the origin one is:

ai_caller = AICaller(model=args.model)

To fix this, I modified the initialization like this:

ai_caller = AICaller(model=args.model, api_base=args.api_base, max_tokens=8192)

This allows the api_base to be correctly passed to the caller.

max_run_time attribute error:
The AICaller requires a max_tokens argument, but this parameter is not present in the parse_args_full_repo function. Also, running the project results in the following error:

Error running CoverAgent for test file '/home/cuso4/qodo-cover/templated_tests/python_fastapi/tests/test_app.py': 'Namespace' object has no attribute 'max_run_time'

This is due to --max-run-time not being defined in the argument parser.

To resolve this, we need to add the following argument:

parser.add_argument(
    "--max-run-time",
    type=int,
    default=300,
    help="Maximum time (in seconds) allowed for test execution. Overrides the value in configuration.toml if provided. Defaults to 300 seconds.",
)

I plan to submit a PR shortly to address these issues. Hope this helps improve the project!
