Add mnesia activity subscription message
A process that calls mnesia:subscribe(activity) will receive the message: {mnesia_activity_event, ActivityID, complete} when any activity that caused a change to a database has finished committing its changes. This allows a subscriber to collect messages already available through the mnesia:subscribe({table, ...}) system to group them as completed transactions.
