This PR adds scaffolding for langchain 1.0 entry package. Most contents have been removed. Currently remaining entrypoints for: * chat models * embedding models * memory -> trimming messages, filtering messages and counting tokens [we may remove this] * prompts -> we may remove some prompts * storage: primarily to support cache backed embeddings, may remove the kv store * tools -> report tool primitives Things to be added: * Selected agent implementations * Selected workflows * Common primitives: messages, Document * Primitives for type hinting: BaseChatModel, BaseEmbeddings * Selected retrievers * Selected text splitters Things to be removed: * Globals needs to be removed (needs an update in langchain core) Todos: * TBD indexing api (requires sqlalchemy which we don't want as a dependency) * Be explicit about public/private interfaces (e.g., likely rename chat_models.base.py to something more internal) * Remove dockerfiles * Update module doc-strings and README.md
