haystack feat: add rendering options for `Pipeline.draw()`

Related Issues

@bilgeyucel and I agree to simplify the diagrams shown in the future tutorials https://colab.research.google.com/drive/1eMfxnsY22NC6nXhh9kBlVK1dgsUurjV6#scrollTo=Tu1bPY3_O5Me and https://colab.research.google.com/drive/1cbHRSSrkadTv-prhnFiG5d9d9RDPCIqu#scrollTo=ze6CrSJSbAl_

Proposed Changes:

Introduces a few parameters to make the pipeline diagram more readable when many components are involved:

show_component_names: whether the name of the component should be shown
show_optional_inputs: whether the optional inputs of the component should be shown
show_connection_types: whether the type of the connections should be shown
direction: whether the plot should be drawn top-down or left-right

Results:

pipe.draw("pipeline.png")

pipeline

pipe.draw("pipeline.png", show_component_names=False, show_optional_inputs=False, show_connection_types=False)

pipeline

pipe.draw("pipeline.png", show_component_names=False, show_optional_inputs=False, show_connection_types=False, direction="left-right")

pipeline

(admittedly not the best example pipeline, but you get the point :smile: )

How did you test it?

Colab notebook, local runs
