8711c612 - core[minor]: Adds an in-memory implementation of RecordManager (#13200)

core[minor]: Adds an in-memory implementation of RecordManager (#13200) **Description:** langchain offers three technologies to save data: - [vectorstore](https://python.langchain.com/docs/modules/data_connection/vectorstores/) - [docstore](https://js.langchain.com/docs/api/schema/classes/Docstore) - [record manager](https://python.langchain.com/docs/modules/data_connection/indexing) If you want to combine these technologies in a sample persistence stategy you need a common implementation for each. `DocStore` propose `InMemoryDocstore`. We propose the class `MemoryRecordManager` to complete the system. This is the prelude to another full-request, which needs a consistent combination of persistence components. **Tag maintainer:** @baskaryan **Twitter handle:** @pprados --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>
