`OpenAIChatCompletionFn` should `__init__` should accept `**kwargs`

[ezraporter]

Describe the bug

Currently the __init__ method for OpenAICompletionFn has **kwargs but OpenAIChatCompletionFn does not. This creates problems if I have both:

• a custom completion function that takes arguments I would like to populate with --completion_args
• a modelgraded eval that I plan to grade with an OpenAI model

In these cases I would like to do:

oaieval my_completion_fn,gpt-4-turbo-preview my_eval --completion_args my_param=my_value

But I get:

TypeError: OpenAIChatCompletionFn.__init__() got an unexpected keyword argument 'my_param'

To Reproduce

Run oaieval gpt-3.5-turbo test-match --completion_args ignore_me=1
