feat(core): add commands to execute VectorStore operations

[mhordynski]

Feature description

VectorStore support in Ragbits needs its own set of developer tools. We should add the following commands:

ragbits vector-store list    # Lists all records in vector store, allow to add where clause
ragbits vector-store query   # Queries a vector store with a string
ragbits vector-store remove  # Deletes data from a vector store

Ways to select VectorStore:

• python path - a path to factory function to import VectorStore from
• yaml config - a path to config which configures VectorStore, optionally it may be in conjuction with DocumentSearch config
• set a default VectorStore in pyproject.toml

^ The same goes with Embeddings

Motivation

Following the Ragbits philosophy, each major component should provide developer tools to make it easier for developers to work with.
