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

Make `LocalAddressSource.LocalAddress` method to return `AddressGroup`. Make
`IsLocalAddress` function to accept parameter of type `AddressGroup`. Adopt
the application code with temporary `GroupFromAddress` helper.

Change type of the `ClientCache.Get` method's parameter to `AddressGroup`.
Use `GroupFromAddress` to call the method from the wrappers in order to no
change their interface.

`network.Address` structure in most cases created once and used read-only.
Replace `AddressFromString` function with `Address.FromString` method with
the same purpose and implementation. Make all libraries to work with value.

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.

Make `Get` method of the wrapper over Container contract's client to
accept binary container ID. Create `Get` function similar to the previous
`Get` variation. Use this function in Container service server in the place
where `Get` method was used.
Additionally implement `AsContainerSource` function which allows
to simply compose container Source interface from the wrapper.

To enable TLS support we can't operate with IP addresses directly.
Certificates are issued with host names so it is required to
pass them into RPC client. DNS resolving should be done by transport
layer and not be a part of node. Therefore `IPAddrString` usage is
removed from code.

Calls to contracts by storage nodes do not lead to the accumulation of
multisignatures in the contract memory, so the call cost can always be
accurately calculated in advance without additional fee.

Add `addContainerAsyncNotificationHandler`
func that passed handler to container's
worker pool similar to how it is done in
reputation handlers.

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.

Replace usage of `cache.ClientCache` type with interface with similar
signature. This will further allow overloading clients without affecting the
logic of dependent packages.

app. Current cache size is set to 100, TTL is 30s (constants).

Implement processing of AnnounceUsedSpace RPC from NeoFS API v2 method on
the app-side according to the following algorithm (except common steps for
each RPC):
* check if the request sender is presented in container;
* check route of the request (compose from signatures);
* pass the value to Writer returned by WriterProvider.

Define component on app-side that implements RemoteWriterProvider with next
logic:
* if ServerInfo is nil, call internal dead end provider;
* if address in ServerInfo equals to local node's address, do nothing;
* otherwise create API client instance via client cache and return the
wrapper over it.

Implement wrapper over netmap and container storages on app-side that builds

* read network map from storage by epoch number;
* build container nodes according to placement policy;
