DiffSyncModel create/update/delete APIs have no logging context

Environment

• DiffSync version: 1.2.0

Proposed Functionality

Extend the DiffSyncModel create, update, and delete APIs with an additional logger parameter, or provide a public log API on the already-included diffsync instance.

Use Case

Currently a DiffSyncModel implementation must construct its own logging context from scratch and lacks access to the context of any surrounding sync operation.
