[nspcc-dev#269] netmap: Return same type from reading methods

There is a need to return similar structure of information about the storage nodes from the contract storage readers. In previous implementation some methods didn't return node state which can differ with the one encoded in the node's BLOB. Define `Node` structure of the information about the storage nodes recorded in the contract storage. Return `[]Node` from all related methods. Also improve docs of touched contract methods.
