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 StorageEngine on app-side that iterates over the
values returned by ListContainers+ContainerSize method pair. Component will
be used as the source of local metrics.

Implement wrapper over netmap and container storages on app-side that builds
placement vectors by next steps:
* read container from storage;
* read network map from storage by epoch number;
* build container nodes according to placement policy;
* build placement vectors with epoch-dependent pivot.

Implement wrapper over API client on app-side that passes used space values
to it. Values are buffered on Put call and sent on Close call.

Implement wrapper over Container contract's client on app-side that passes
used space values to it. Uses a fixed public key, whose value will be the
key of the local storage node.

To run storage node at dev-env environment it should have
configurable parameters. To keep `cfg` structures we can
read configuration from env and yml config file with viper
and parse values such as script hashes, fees, keys into
`cfg` structures.
