Ollama: support streaming

[anakin87]

Ollama Generator should support streaming, as done in other Generators with streaming_callback: see for example OpenAIGenerator.

@anakin87 I can give this a go

Also seems like the official python client for ollama was published few days back ollama-python, I would suggest to check that out and use it in OllamaXXX components.

Hey @sachinsachdeva , what do you think? I usually advise caution with developing against something that's tagged as experimental

[anakin87]

In my opinion, in the future, the most appropriate choice might be to adopt the official python client.
For now, there is no hurry.
