Add temperature to ChatOpenAI (#2152)

Browse Source 
Just add `temperature` parameter to ChatOpenAI class.


https://python.langchain.com/en/latest/getting_started/getting_started.html#building-a-language-model-application-chat-models
There are descriptions like `chat = ChatOpenAI(temperature=0)` in the
documents, but it is confusing because it is not supported as an
explicit parameter.
