pydantic/json parsing (#1722)
```
class Joke(BaseModel):
    setup: str = Field(description="question to set up a joke")
    punchline: str = Field(description="answer to resolve the joke")

joke_query = "Tell me a joke."

# Or, an example with compound type fields.
#class FloatArray(BaseModel):
#    values: List[float] = Field(description="list of floats")
#
#float_array_query = "Write out a few terms of fiboacci."

model = OpenAI(model_name='text-davinci-003', temperature=0.0)
parser = PydanticOutputParser(pydantic_object=Joke)
prompt = PromptTemplate(
    template="Answer the user query.\n{format_instructions}\n{query}\n",
    input_variables=["query"],
    partial_variables={"format_instructions": parser.get_format_instructions()}
)

_input = prompt.format_prompt(query=joke_query)
print("Prompt:\n", _input.to_string())
output = model(_input.to_string())
print("Completion:\n", output)
parsed_output = parser.parse(output)
print("Parsed completion:\n", parsed_output)
```

```
Prompt:
 Answer the user query.
The output should be formatted as a JSON instance that conforms to the JSON schema below.  For example, the object {"foo":  ["bar", "baz"]} conforms to the schema {"foo": {"description": "a list of strings field", "type": "string"}}.

Here is the output schema:
---
{"setup": {"description": "question to set up a joke", "type": "string"}, "punchline": {"description": "answer to resolve the joke", "type": "string"}}
---

Tell me a joke.

Completion:
 {"setup": "Why don't scientists trust atoms?", "punchline": "Because they make up everything!"}

Parsed completion:
 setup="Why don't scientists trust atoms?" punchline='Because they make up everything!'
```

Ofc, works only with LMs of sufficient capacity. DaVinci is reliable but
not always.

Adding ability to return_pl_id to all PromptLayer Models in LangChain (#1699)
PromptLayer now has support for [several different tracking
features.](https://magniv.notion.site/Track-4deee1b1f7a34c1680d085f82567dab9)
In order to use any of these features you need to have a request id
associated with the request.

In this PR we add a boolean argument called `return_pl_id` which will
add `pl_request_id` to the `generation_info` dictionary associated with
a generation.

We also updated the relevant documentation.

fallback to {} for None metadata from Chroma (#1714)
The basic vector store example started breaking because `Document`
required `not None` for metadata, but Chroma stores metadata as `None`
if none is provided. This creates a fallback which fixes the basic
tutorial
https://langchain.readthedocs.io/en/latest/modules/indexes/examples/vectorstores.html

Here is the error that was generated

```

Implement basic metadata filtering in Qdrant (#1689)
This PR implements a basic metadata filtering mechanism similar to the
ones in Chroma and Pinecone. It still cannot express complex conditions,
as there are no operators, but some users requested to have that feature

feat: allow the unstructured kwargs to be passed in to Unstructured document loaders (#1667)
### Summary

Allows users to pass in `**unstructured_kwargs` to Unstructured document
loaders. Implemented with the `strategy` kwargs in mind, but will pass
in other kwargs like `include_page_breaks` as well. The two currently
supported strategies are `"hi_res"`, which is more accurate but takes
longer, and `"fast"`, which processes faster but with lower accuracy.
The `"hi_res"` strategy is the default. For PDFs, if `detectron2` is not
available and the user selects `"hi_res"`, the loader will fallback to
using the `"fast"` strategy.


### Testing

#### Make sure the `strategy` kwarg works

Run the following in iPython to verify that the `"fast"` strategy is
indeed faster.

```python
from langchain.document_loaders import UnstructuredFileLoader

loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", strategy="fast", mode="elements")
%timeit loader.load()

loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", mode="elements")
%timeit loader.load()
```

On my system I get:

```python
In [3]: from langchain.document_loaders import UnstructuredFileLoader

In [4]: loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", strategy="fast", mode="elements")

In [5]: %timeit loader.load()
247 ms ± 369 µs per loop (mean ± std. dev. of 7 runs, 1 loop each)

In [6]: loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", mode="elements")

In [7]: %timeit loader.load()
2.45 s ± 31 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
```

#### Make sure older versions of `unstructured` still work

Run `pip install unstructured==0.5.3` and then verify the following runs
without error:

```python
from langchain.document_loaders import UnstructuredFileLoader

loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf",  mode="elements")
loader.load()
```

sql: do not hard code the LIMIT clause in the table_info section (#1563)
Seeing a lot of issues in Discord in which the LLM is not using the
correct LIMIT clause for different SQL dialects. ie, it's using `LIMIT`
for mssql instead of `TOP`, or instead of `ROWNUM` for Oracle, etc.
I think this could be due to us specifying the LIMIT statement in the
example rows portion of `table_info`. So the LLM is seeing the `LIMIT`
statement used in the prompt.
Since we can't specify each dialect's method here, I think it's fine to
just replace the `SELECT... LIMIT 3;` statement with `3 rows from
table_name table:`, and wrap everything in a block comment directly
following the `CREATE` statement. The Rajkumar et al paper wrapped the
example rows and `SELECT` statement in a block comment as well anyway.
Thoughts @fpingham?

cleanup: unify 3 different pdf loaders, rename PagedPDFSplitter (#1615)
`OnlinePDFLoader` and `PagedPDFSplitter` lived separate from the rest of
the pdf loaders.

Because they're all similar, I propose moving all to `pdy.py` and the
same docs/examples page.

Additionally, `PagedPDFSplitter` naming doesn't match the pattern the
rest of the loaders follow, so I renamed to `PyPDFLoader` and had it
inherit from `BasePDFLoader` so it can now load from remote file
sources.

Add regex dict: (#1616)
This class enables us to send a dictionary containing an output key and
the expected format, which in turn allows us to retrieve the result of
the matching formats and extract specific information from it.

To exclude irrelevant information from our return dictionary, we can
prompt the LLM to use a specific command that notifies us when it
doesn't know the answer. We refer to this variable as the
"no_update_value".

Regarding the updated regular expression pattern
(r"{}:\s?([^.'\n']*).?"), it enables us to retrieve a format as 'Output
Key':'value'.

We have improved the regex by adding an optional space between ':' and
'value' with "s?", and by excluding points and line jumps from the
matches using "[^.'\n']*".

Add read only shared memory (#1491)
Provide shared memory capability for the Agent.
Inspired by #1293 .

## Problem

If both Agent and Tools (i.e., LLMChain) use the same memory, both of
them will save the context. It can be annoying in some cases.


## Solution

Create a memory wrapper that ignores the save and clear, thereby
preventing updates from Agent or Tools.
