Provide relevant tokens to migrate events
Problem/Motivation
The `migrate` ECA sub-module provides useful migration related events, but it doesn't appear that the relevant migration data is exposed as tokens. Things like information about the running migration, the migration row being processed, and the migrate message being saved, are some examples.
Proposed resolution
Exposed relative migration data as tokens for migration events.
