Add version, template_dict, attachments and 'core arguments' as arguments.

if version is not 1.0, return unsupported version error.

replace template_dict[key] in final prompt with template_dict[value].

'attachments' is a list of GCS files. Attach these to the message.

'core arguments' are "temperature", "max_tokens", "top_p", "frequency_penalty", and "presence_penalty" which are directly used as arguments to the openai api.

- same as Test II
