Chroma persistence (#1028) 
This PR adds persistence to the Chroma vector store.

Users can supply a `persist_directory` with any of the `Chroma` creation
methods. If supplied, the store will be automatically persisted at that
directory.

If a user creates a new `Chroma` instance with the same persistence
directory, it will get loaded up automatically. If they use `from_texts`
or `from_documents` in this way, the documents will be loaded into the
existing store.

There is the chance of some funky behavior if the user passes a
different embedding function from the one used to create the collection
- we will make this easier in future updates. For now, we log a warning.

Added retry for openai.error.ServiceUnavailableError (#1022) 
Imho retries should be performed for ServiceUnavailableError (which

Chroma in LangChain (#1010) 
Chroma is a simple to use, open-source, zero-config, zero setup
vectorstore.

Simply `pip install chromadb`, and you're good to go. 

Out-of-the-box Chroma is suitable for most LangChain workloads, but is
highly flexible. I tested to 1M embs on my M1 mac, with out issues and
reasonably fast query times.

Look out for future releases as we integrate more Chroma features with
LangChain!

Import of declarative_base when SQLAlchemy <1.4 (#883) 
In
[pyproject.toml](https://github.com/hwchase17/langchain/blob/master/pyproject.toml),
the expectation is `SQLAlchemy = "^1"`. But, the way `declarative_base`
is imported in
[cache.py](https://github.com/hwchase17/langchain/blob/master/langchain/cache.py)
will only work with SQLAlchemy >=1.4. This PR makes sure Langchain can
be run in environments with SQLAlchemy <1.4

improves huggingface_hub example (#988) 
The provided example uses the default `max_length` of `20` tokens, which
leads to the example generation getting cut off. 20 tokens is way too
short to show CoT reasoning, so I boosted it to `64`.

Without knowing HF's API well, it can be hard to figure out just where
those `model_kwargs` come from, and `max_length` is a super critical
one.

from langchain.document_loaders import UnstructuredURLLoader

urls = [
    "https://www.understandingwar.org/backgrounder/russian-offensive-campaign-assessment-february-8-2023",
    "https://www.understandingwar.org/backgrounder/russian-offensive-campaign-assessment-february-9-2023"

Update readthedocs.py (#943) 
Sometimes, the docs may be empty. For example for the text =
soup.find_all("main", {"id": "main-content"}) was an empty list. To
cater to these edge cases, the clean function needs to be checked if it
is empty or not.

Add asyncio support for LLM (OpenAI), Chain (LLMChain, LLMMathChain), and Agent (#841) 
Supporting asyncio in langchain primitives allows for users to run them
concurrently and creates more seamless integration with
asyncio-supported frameworks (FastAPI, etc.)

Summary of changes:

**LLM**
* Add `agenerate` and `_agenerate`
* Implement in OpenAI by leveraging `client.Completions.acreate`

**Chain**
* Add `arun`, `acall`, `_acall`
* Implement them in `LLMChain` and `LLMMathChain` for now

**Agent**
* Refactor and leverage async chain and llm methods
* Add ability for `Tools` to contain async coroutine
* Implement async SerpaPI `arun`

Create demo notebook.

Open questions:
* Should all the async stuff go in separate classes? I've seen both
patterns (keeping the same class and having async and sync methods vs.
having class separation)
