IdStory Identity Manager

When notification is sent only to some subset of recipients (for example because of invalid email address or non existent phone number), then administrator should be able to see which recipients were not notified.

Feature will be implemented in such way, that when notification is sent, one IdmNotificationLog is persisted with all recipients, but also concrete logs (websocketLog, emailLog...) are persisted for each recipient bearing information about whether the notification was sent and when.
