feat: Standardize error handling across vector stores

[mackurzawa]

Feature description

We want to ensure that all vector stores throw similar errors. Currently, different vector stores throw their own specific errors when certain methods fail. For example, the chroma vector store can throw a specific error when the remove() method is called and fails, while the qdrant vector store throws a different error for the same situation.

The task would involve mapping the errors thrown by different vector stores to a set of generic errors.

Motivation

Standardizing error handling across vector stores will simplify error management, by allowing developers to use try/except blocks on any vector store without changing the exception type depending on the implementation. Developers will be able to handle errors in a consistent manner, regardless of the vector store implementation.
