This occurred when redis_url was not passed as a parameter even though a
REDIS_URL env variable was present.
This occurred for all methods that eventually called any of:
(from_texts, drop_index, from_existing_index) - i.e. virtually all
methods in the class.
This fixes it

I think it's not polite for a library to use the root logger
both of these forms are also used:
```
logger = logging.getLogger(__name__)
logger = logging.getLogger(__file__)
```
I am not sure if there is any reason behind one vs the other? (...I am
guessing maybe just contributed by different people)
it seems to me it'd be better to consistently use
`logging.getLogger(__name__)`
this makes it easier for consumers of the library to set up log
handlers, e.g. for everything with `langchain.` prefix
Avoid using placeholder methods that only perform a `cast()`
operation because the typing would otherwise be inferred to be the
parent `VectorStore` class. This is unnecessary with TypeVar's.
This PR fixes a logic error in the Redis VectorStore class
Creating a redis vector store `from_texts` creates 1:1 mapping between
the object and its respected index, created in the function. The index
will index only documents adhering to the `doc:{index_name}` prefix.
Calling `add_texts` should use the same prefix, unless stated otherwise
in `keys` dictionary, and not create a new random uuid.
