Use the client to customize API keys / workspace ocnnections, SSl certs,

feedback (~metrics), projects (tracer sessions/groups), etc.

Parameters
----------

API key for the LangSmith API. Defaults to the LANGCHAIN_API_KEY
environment variable.
retry_config : Retry or None, default=None
Retry configuration for the HTTPAdapter.
timeout_ms : int, tuple[int, int], or None, default=None
Timeout for the HTTPAdapter. Can also be a 2-tuple of

web_url : str or None, default=None
URL for the LangSmith web app. Default is auto-inferred from
the ENDPOINT.
session: requests.Session or None, default=None
The session to use for requests. If None, a new session will be
created.
anonymizer : Optional[Callable[[dict], dict]]
A function applied for masking serialized run inputs and outputs,
before sending to the API.
hide_inputs: Whether to hide run inputs when tracing with this client.
If True, hides the entire inputs. If a function, applied to
all run inputs when creating runs.
hide_outputs: Whether to hide run outputs when tracing with this client.
If True, hides the entire outputs. If a function, applied to
all run outputs when creating runs.
