In previous implementation Inner Ring allowed storage nodes with any state to register in the network. According to the current design, only nodes with ONLINE state are allowed to enter the network map. Create new `state` sub-package of `nodevalidation` package of Inner Ring application. Define `state.NetMapCandidateValidator` type and provide `NodeValidator` interface required by the Inner Ring's processor of `Netmap` contract's notification events. Embed new validator into the one used by the Inner Ring application. From now all `AddPeer` notifications with node state other than `ONLINE` will be denied.
