interfaces. Each interface calls the same RPC handler.

There is a need to support multiple server endpoints for reputation and
container transmission.
Replace `ServerInfo.Address` getter with `ServerInfo.IterateAddresses`
iterator.

Implement `Address.WriteToNodeInfo` method which sets address of `NodeInfo`
structure. Use it in storage node application.

Also use neo-go private key wrapper where possible, as it
already has methods for (un)marshaling.

Config `NodeInfo` should be used for bootstrap. Separete local node info and
netmap one. Return configured `NodeInfo` if structure from netmap is
missing.

Implement function `fatalOnErrDetails` similar to `fatalOnErr` but accepting
string details that are written to log output. Use the function everywhere
in application code without wrapping in an if-else statement.

Wrap functions at `pkg/errors` return nil if error argument
was nil. fmt.Errorf always returns error so we need to add
missing error checks to the code.

From now non-relay node always sends re-bootstrap transaction every 2 epochs
starting from the boot-up epoch.

Application can be shut down often, it is undesirable to send status changes
on a transaction every time. Control API should be used before shutdown for
this purpose.

Control service turns storage node to online and offline modes. We can't
reuse `cfgNetmap.reBootstrapEnabled` because it represents configuration
value while control service manages state in runtime.

Add handler closure over worker pool
in the event package.
Add `addNewEpochAsyncNotificationHandler`
function that uses that closure. Pass
the reputation report handler to worker
pool via using that function.

Implement `NetworkInfo` calls on full stack of Netmap services. Current
epoch is read from node local state, magic number is read via `MagicNumber`
call of morph client.

At startup, update only node info status. Leave all other
attributes from node configuration, so user can update them.

Implement NodeState interface required by Netmap service. Make a single
point of updating the state of the node (for both Netmap and Control
services). Protect node info structure from data race.

Call Netmap contract on SetNetmapStatus rpc of Control service (AddPeer
method if new status is ONLINE, UpdatePeerState method otherwise).

Update node network status via update status by getting the latest network
map and finding the node in it. This step is performed at the start of the
application and upon notification of a new epoch.

Implement HealthChecker on node app structure. Set health status to ONLINE
after node boot. Set health status to OFFLINE on shutdown.

Transfer the state of the node to offline when the application is shut down.
Updating the state is done by calling UpdateState method of Netmap contract.
