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.

In previous implementation Container service handlers didn't cache the
results of `Get` / `GetEACL` / `List` operations. As a consequence of this,
high load on the service caused neo-go client's connection errors. To avoid
this there is a need to use cache. Object service already uses `Get` and
`GetEACL` caches.
Implement cache of `List` results. Share already implemented cache of Object
service with the Container one. Provide new instance of read-only container
storage (defined as an interface)to morph executor's constructor on which
container service is based. Write operations remained unchanged.

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 `Router` to the reputation server. `Router` is
