Renamed from test to exec
Added description and changed emails to to bcc
Ticket: KMS-974 #
Enable null values on to, cc, bcc and replyTo
Adding user parameters is not needed (for now)
Added permission items for KalturaEventNotificationTemplate attributes
Wrapped the HTTP notification with new KalturaHttpNotification object
Constructor removed from parent class
Update the job id in the job data.
The job id used later as part of the notification data.
Dispatch method is protected by permissions, no need to disable it.
Only arrays can't be set to null.
It's needed because we want to be able to unset to, cc, bcc and replyTo
on email-notification-template objects.
