Notification userid

[sleidig]

see #2847

Make userId available on NotificationConfig entity because replication-backend cannot have a placeholder in combination with normal text (yet)

i.e.
possible:

{
  "subject": "NotificationConfig",
  "action": "manage",
  "conditions": {
    "userId": "${user.id}"
  }
},

not supported in backend:

{
  "subject": "NotificationConfig",
  "action": "manage",
  "conditions": {
    "_id": "NotificationConfig:${user.id}"
  }
},
