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.

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.

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.
