client = chromadb.Client()

The Chroma backend Client can be provided with Settings when initializing. (See https://docs.trychroma.com/reference/python/client#client)
If we want to change these using the haystack integration we have to illegally access the private _client like so:

db = ChromaDocumentStore()
db._client.get_settings().anonymized_telemetry = False

It would be preferable to offer a way to pass Client Settings to the ChromaDocumentStore constructor.
