Introduce Blob and Blob Loader interface (#3603)
This PR introduces a Blob data type and a Blob loader interface.

This is the first of a sequence of PRs that follows this proposal: 

https://github.com/hwchase17/langchain/pull/2833

The primary goals of these abstraction are:

* Decouple content loading from content parsing code.
* Help duplicated content loading code from document loaders.
* Make lazy loading a default for langchain.

enhancement: add elements mode to UnstructuredURLLoader (#3456)
### Summary

Updates the `UnstructuredURLLoader` to include a "elements" mode that
retains additional metadata from `unstructured`. This makes
`UnstructuredURLLoader` consistent with other unstructured loaders,
which also support "elements" mode. Patched mode into the existing
`UnstructuredURLLoader` class instead of inheriting from
`UnstructuredBaseLoader` because it significantly simplified the
implementation.

### Testing

This should still work and show the url in the source for the metadata

```python
from langchain.document_loaders import UnstructuredURLLoader

urls = ["https://www.understandingwar.org/sites/default/files/Russian%20Offensive%20Campaign%20Assessment%2C%20April%2011%2C%202023.pdf"]

loader = UnstructuredURLLoader(urls=urls, headers={"Accept": "application/json"}, strategy="fast")
docs = loader.load()
print(docs[0].page_content[:1000])
docs[0].metadata
``` 

This should now work and show additional metadata from `unstructured`.

This should still work and show the url in the source for the metadata

```python
from langchain.document_loaders import UnstructuredURLLoader

urls = ["https://www.understandingwar.org/sites/default/files/Russian%20Offensive%20Campaign%20Assessment%2C%20April%2011%2C%202023.pdf"]

loader = UnstructuredURLLoader(urls=urls, headers={"Accept": "application/json"}, strategy="fast", mode="elements")
docs = loader.load()
print(docs[0].page_content[:1000])
docs[0].metadata

Allow clearing cache and fix gptcache (#3493)
This PR

* Adds `clear` method for `BaseCache` and implements it for various
caches
* Adds the default `init_func=None` and fixes gptcache integtest
* Since right now integtest is not running in CI, I've verified the
changes by running `docs/modules/models/llms/examples/llm_caching.ipynb`
(until proper e2e integtest is done in CI)

Fix/issue 2695 (#3608)
## Background
fixes #2695  

## Changes
The `add_text` method uses the internal embedding function if one was
passes to the `Weaviate` constructor.
NOTE: the latest merge on the `Weaviate` class made the specification of
a `weaviate_api_key` mandatory which might not be desirable for all
users and connection methods (for example weaviate also support Embedded
Weaviate which I am happy to add support to here if people think it's
desirable). I wrapped the fetching of the api key into a try catch in
order to allow the `weaviate_api_key` to be unspecified. Do let me know
if this is unsatisfactory.

## Test Plan
added test for `add_texts` method.

new example: multiagent dialogue with decentralized speaker selection (#3629)
This notebook showcases how to implement a multi-agent simulation
without a fixed schedule for who speaks when. Instead the agents decide
for themselves who speaks. We can implement this by having each agent
bid to speak. Whichever agent's bid is the highest gets to speak.

We will show how to do this in the example below that showcases a
fictitious presidential debate.

Arxiv document loader (#3627)

- sorted `__all__` in `__init__.py` (otherwise it is hard to find a

Close dataframe column names are being treated as one by the LLM (#3611)
We are sending sample dataframe to LLM with df.head().
If the column names are close by, LLM treats two columns names as one,
returning incorrect results.


![image](https://user-images.githubusercontent.com/4707543/234678692-97851fa0-9e12-44db-92ec-9ad9f3545ae2.png)

In the above case the LLM uses **Org Week** as the column name instead
of **Week** if asked about a specific week.

Returning head() as a markdown separates out the columns names and thus
using correct column name.

Fix Replicate llm response to handle iterator / multiple outputs (#3614)
One of our users noticed a bug when calling streaming models. This is
because those models return an iterator. So, I've updated the Replicate
`_call` code to join together the output. The other advantage of this
fix is that if you requested multiple outputs you would get them all –
previously I was just returning output[0].

I also adjusted the demo docs to use dolly, because we're featuring that
model right now and it's always hot, so people won't have to wait for
the model to boot up.

The error that this fixes:
```
> llm = Replicate(model=“replicate/flan-t5-xl:eec2f71c986dfa3b7a5d842d22e1130550f015720966bec48beaae059b19ef4c”)

- I also went through all other files in agent directory. no seeing any
other missing piece. (there are several prompt strings not annotated,

read in terms of indents.) Anyway, I think this is the last PR in

example: multi player dnd (#3560)
This notebook shows how the DialogueAgent and DialogueSimulator class
make it easy to extend the [Two-Player Dungeons & Dragons
example](https://python.langchain.com/en/latest/use_cases/agent_simulations/two_player_dnd.html)
to multiple players.

The main difference between simulating two players and multiple players
is in revising the schedule for when each agent speaks

To this end, we augment DialogueSimulator to take in a custom function
that determines the schedule of which agent speaks. In the example
below, each character speaks in round-robin fashion, with the
storyteller interleaved between each player.

Notebook example: Context-Aware AI Sales Agent (#3547)
I would like to contribute with a jupyter notebook example
implementation of an AI Sales Agent using `langchain`.

The bot understands the conversation stage (you can define your own
stages fitting your needs)
using two chains:

1. StageAnalyzerChain - takes context and LLM decides what part of sales
conversation is one in
2. SalesConversationChain - generate next message

Schema:

https://images-genai.s3.us-east-1.amazonaws.com/architecture2.png

my original repo: https://github.com/filip-michalsky/SalesGPT

This example creates a sales person named Ted Lasso who is trying to
sell you mattresses.

Happy to update based on your feedback.

docs: simplification of two agent d&d simulation (#3550)
Simplifies the [Two Agent
D&D](https://python.langchain.com/en/latest/use_cases/agent_simulations/two_player_dnd.html)
example with a cleaner, simpler interface that is extensible for
multiple agents.

`DialogueAgent`:
- `send()`: applies the chatmodel to the message history and returns the
message string
- `receive(name, message)`: adds the `message` spoken by `name` to
message history

The `DialogueSimulator` class takes a list of agents. At each step, it
performs the following:
1. Select the next speaker
2. Calls the next speaker to send a message 
3. Broadcasts the message to all other agents
4. Update the step counter.
The selection of the next speaker can be implemented as any function,
but in this case we simply loop through the agents.
