BootstrapFewShot failing due to lm.copy for AzureOpenAI

[insop]

Summary

BootstrapFewShot failing due to lm.copy for AzureOpenAI, likely due to positional argument issue from recent changes.

Environment

• code: 98304a2
• model azure openai

Error message

• during BootstrapFewShot run, code errored out due to missing arguments, api_version

>[dspy/dsp/modules/lm.py](https://file+.vscode-resource.vscode-cdn.net//dspy/dsp/modules/lm.py)(106)copy()
    102         model = kwargs.pop('model')
    105 
--> 106         return self.__class__(model, **kwargs)

Analysis

AzureOpenAI expects positional arguments, so it is failing.
I will add my fixes and see if that will impact other models.

class AzureOpenAI(LM):
...

    def __init__(
        self,
        api_base: str,
        api_version: str,
        model: str = "gpt-3.5-turbo-instruct",
        api_key: Optional[str] = None,
        model_type: Literal["chat", "text"] = "chat",
        **kwargs,
    ):

(updated since previous note was not valid)

I tested with this PR (#584) and I still hit the issue #521.
For my setup, I use llm_metric and teach lm that are all azure model and saw this error when I am using BootstrapFewShotWithRandomSearch

<function llm_metric at 0xxx> due to __init__() missing 2 required positional arguments: 'api_base' and 'api_version'.

But let's get this change in first, and I will figure out how to address #521
