Add FilterQuery

[Spartee]

Add a FilterQuery class for running just a query with a filter and no vector search in the case where the user needs to do this and should not have to also use Redis-py

Example

>>> from redisvl.query import FilterQuery
>>> from redisvl.query.filter import Tag
>>> t = Tag("brand") == "Nike"
>>> q = FilterQuery(return_fields=["brand", "price"], filter_expression=t)

LGTM!

we will eventually need to add TLS support here in the form of a path to the server CA, and client/user certs (public and private) too. With the bedrock launch coming, it would be great to push users here for an easier onboarding :)
