@pchalasani I'll fix the linting issue if there are no concerns about the current implementation

> I don't want to bring in vbls specific to `AzureGPTConfig` subclass into `OpenAIGPTConfig` agreed, but we can make it as a tmp solution, till we figure out a better...

or we can move these variables to the `OpenAIGPTConfig` and remove them from `AzureGPTConfig `

is there a specific use case?

I can work on this issue if it's not assigned yet

for a variable [`use_functions_api`][langroid.agent.chat_agent.ChatAgentConfig]??
