Some software components regulate the way of working with placement arrays
when a local node enters it. In the previous implementation, the locality
criterion was the correspondence between the announced network address
(group) and the address with which the node was configured. However, by
design, network addresses are not unique identifiers of storage nodes in the
system.
Change comparisons by network addresses to comparisons by keys in all
packages with the logic described above. Implement `netmap.AnnouncedKeys`
interface on `cfg` type in the storage node application.

Generalize single gRPC interface of the storage node to a group of
interfaces. Each interface calls the same RPC handler.

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

Includes:
- Delete first `ctx` argument in `Write` method.
- Move intermediate Initial trust struct and method
to `calculator` file.
- Change Alpha to 0.1.

Init all wrappers eigenTrust algorithm needed in
`main` packages. Implement `SendIntermediateResult`
GRPC method of `reputationServer`.

Eigen trust block timer ticks to start new round of
eigen trust calculations. Every epoch this timer
recalculates duration and starts again.

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.

Add `Router` to the reputation server. `Router` is
called on every incoming request and inits `Writer`
that sends `Trust`s to the next route point or
handle(logs in that implementation) them if current
node is the end point of the route.
Rename `onlyKeyRemoteServerInfo` struct for container
to separate it from the same implementation of the
same `ServerInfo` interface for reputation.

Implement dependencies for local trust router
in `main` package. Managers are defined as
next node after the current one in HRW sorted
list of current NetMap.

Register reputation service server that:
* verifies signatures of the requests and signs the responses;
* attaches response meta header to the responses;
* logs body structures of the requests (only as initial implementation, in
future it will be replaces with local trust storage).

Implement and call `initReputationService` func that constructs local trust
storage and controller, and subscribes the controller on new epoch
notification. Event handler calls `Controller.Report` method to process
collected values.

Implement simple `WriterProvider` building a `Writer` that writes incoming
data to the log. In the future, this action will be replaced by sending the
value to the manager nodes.

Implement iterator provider on wrapper over the local trust storage.
Provided iterator passes normalized local trust values according to original
EigenTrust algorithm description. In the borderline case, normalized values
are set as 1/N, N - number of remote nodes in network map.
