Background & Motivation

There is an internal use case to check for a field in server error replies.

This field is not exposed by any of the existing error types: CommandError, WriteError, WriteException, BulkWriteException.

Scope
Expose the full server reply in error types.

Investigate possible options for exposing this API.

Consider adding a method to the ServerError interface.

An alternative is to return a wrapped error containing the full server reply.
