Vectorizer runtime config

[dirkkul]

Closes #382

Adds the possibility of typed input for runtime module configuration of api-keys, rate limits and other things that can be affected by headers at the request time.

Currently only adds this for OpenAI, Cohere and VoyageAI as these two are already supported by the batch vectorization and need the rate-limit input.

Also adds some tuning of the dynamic batching for low-rate-limit api keys

Syntax:

    collection = client.collections.create(
        name="Test",
        properties=[
            wvc.config.Property(name="url", data_type=wvc.config.DataType.TEXT),
            wvc.config.Property(name="title", data_type=wvc.config.DataType.TEXT),
            wvc.config.Property(name="raw", data_type=wvc.config.DataType.TEXT),
            wvc.config.Property(name="sha", data_type=wvc.config.DataType.TEXT),
        ],
        vectorizer_config=[
            wvc.config.Configure.NamedVectors.text2vec_cohere(name="cohereFirst"),
            wvc.config.Configure.NamedVectors.text2vec_cohere(name="cohereSecond"),
        ]
    )
integrations=[
            wvc.init.Integrations.cohere(
                api_key="KEY"
            ),
            wvc.init.Integrations.openai(
                api_key="KEY", base_url ="...."
            ),
            wvc.init.Integrations.voyageai(
                api_key="KEY",
            ),
        ]
client.integrations.configure(integrations)
