If another file anywhere in `unit_tests` sets `langchain.verbose =
True`, it messes up all of the tests that check for no callbacks because
the `None` for verbose gets overridden by the global verbosity flag. By
explicitly setting it in unit tests, we bypass that potential issue
I noticed (after publication) that the getting_started link on the main
page was borked. This should fix it.

Big docs refactor! Motivation is to make it easier for people to find
resources they are looking for. To accomplish this, there are now three
main sections:
- Getting Started: steps for getting started, walking through most core
functionality
- Modules: these are different modules of functionality that langchain
provides. Each part here has a "getting started", "how to", "key
concepts" and "reference" section (except in a few select cases where it
didnt easily fit).
- Use Cases: this is to separate use cases (like summarization, question
answering, evaluation, etc) from the modules, and provide a different
entry point to the code base.
There is also a full reference section, as well as extra resources
(glossary, gallery, etc)

1. remove verbose from someplace it didnt relaly belong
2. everywhere else, make verbose Optional[bool] with default to None
3. make base classes accept None, and then look up globabl verbosity if
thats the case
first pass at stdout callback
for the most part, went pretty smoothly. aside from the code here, here
are some comments/observations.
1.
should somehow default to stdouthandler so i dont have to do
```
from langchain.callbacks import get_callback_manager
from langchain.callbacks.stdout import StdOutCallbackHandler
get_callback_manager().add_handler(StdOutCallbackHandler())
```
2. I kept around the verbosity flag. 1) this is pretty important for
getting the stdout to look good for agents (and other things). 2) I
actually added this for LLM class since it didn't have it.
3. The only part that isn't basically perfectly moved over is the end of
the agent run. Here's a screenshot of the new stdout tracing

Noticing it is missing logging of the final thought, eg before this is
what it looked like

The reason its missing is that this was previously logged as part of
agent end (lines 205 and 206)
this is probably only relevant for the std out logger? any thoughts for
how to get it back in?
