Add migration_id token to migrate events
Problem/Motivation
I have a workflow that needs to trigger an action only when a particular migration has finished importing. Currently, the tokens provided by the migration events in eca_migrate don't expose the migration's plugin id, so there is no way to know which migration is executing.
Proposed resolution
Add a 'migration_id' token to the 'migration' ECA event that returns the id of the executing migration.
