Allow `ConversationalPipeline` to receive string input about transformers HOT 3 CLOSED

Hi @mattdeeperinsights, we're actually deprecating the ConversationalPipeline in favour of the TextGenerationPipeline. ConversationalPipeline will be removed in the very near future, but you can now pass chats directly to TextGenerationPipeline instead.

Unfortunately, this means that your shortcut won't work that well - I think it would have been reasonably clean for ConversationalPipeline, but TextGenerationPipeline interprets a single string as a naked string to be completed, rather than a user message.

okay thanks that makes sense.

It turns out that later version of the pipeline has the expected behaviour anyway, so I will stick to that:

transformers.pipeline(
    task='text-generation',
    model=MODEL,
    tokenizer=TOKENIZER,
)

A string input here will be embedded into a conversation behind the scenes
