Feature request

When I am using VLLM using langchain, it shows a progress bar for each input. I read the code of VLLM and Langchain (link) on GitHub and I understood that in line 133, there is parameter called use_tqdm that should be False to disable it but there is no option to disable it using Langchain. Add a new parameters to handle it.

Motivation

My motivation is that enable/disable of progress bar should be optional because it affect on the appearance of applications.
