etl: removed fk that cause deadlock occasionally
Deadlock in user sync causes failures in collections and
aggregation. The users details sync is done every minute locking
the row for update, once a hour the hourly aggregation tries to
sync VM data containing users foreign key which causes deadlock
due to wait on the users table update.
To pervent for now we will drop fk.
