chore: Optimizing the method getOptionalParams in HasOpenAITextParams

[FarrukhMasud]

Related Issues/PRs

The method getOptionalParams in HasOpenAITextParams was implemented in such a way that for every row in the data frame it will:

1. Create a List of all shared text parameter except logprobs
2. Call flatMap on each element in list to get optional parameters with snake-case name
3. Create one more list with just logprobs parameter
4. Call flatMap on this single element list
5. Compbine this new tuple with the other list
6. Convert this list of tuple to Map and return

We can do better to make code cleaner and more readable.

What changes are proposed in this pull request?

One of the reason for creating a list of all shared text parameters except logprobs is that we wanted to name these parameters in snake-case. We can do this while creating parameter object, hence no need to call method to generate snake-case for every iteration. This way we can put all parameters in a single list.

How is this patch tested?

Since this essentially just refactoring the code, I have tested this by running the tests. Existing tests should validate that the code is working as expected
