[DX] Save a Collection's objects into a local JSON file

[CShorten]

What?

Get the objects from a Collection in Weaviate and to a local JSON file.

Why?

This helps with quick experimentation, maybe other use cases.

How?

Thinking this API:

collection = client.collections.get("WineReview")

collection.to_json(savepath="wine_reviews.json", num_samples=100) # returns bool success/fail

That pretty much just wraps the cursor API,

collection = client.collections.get("WineReview")

for item in collection.iterator():
    print(item.uuid, item.properties)

And then dumps the JSON file with the savepath.

Maybe also makes the json Python library another dependency of Weaviate's Python Client (if not already).
