[#236] *: Notify user on success

Add notifications to:
- container put, delete, setEACL
- netmap addPeer, updateState

Because notifications are limited in size (currently arguments should be
less than 1024 bytes) provide only minimal information, such as entity
ID (container ID or node public key).
