Add ChromaDB knowledge base

[hoxsec]

Hi guys,

Tried implementing this feature, however I'm getting stuck at the following mypy test:

error: Function "chromadb.Client" is not valid as a type [valid-type]

@property
    def client(self) -> chromadb.Client:
        if self._client is None:
            return chromadb.Client(
                namespace=self.namespace,
                hostname=self.hostname,
                port=self.port,
                headers=self.headers,
                ssl=self.ssl,
            )
        return self._client
