In previous implementation storage node responded with the outdated
container list after successful creation/removal up until cache
invalidation due to TTL. In order to decrease the probability of
outdated responses node should update its cache on event receipts.
Implement `ttlContainerLister.update` method which actualizes cached
list of the owner's containers. Make node to call `update` method
on `PutSuccess`/`DeleteSuccess` notifications from the `Container`
contract.

In previous implementation storage node responded with the removed
container up until cache invalidation due to TTL. In order to avoid
false-positive responses node should update its cache on `DeleteSuccess`
events.
Make node to call `handleRemoval` method of the container cache which
leads to subsequent `apistatus.ErrContainerNotFound` errors.

In previous implementation failed requests to the Sidechain weren't
cached. It makes sense to cache errors along with the values in order to
decrease potential load spikes onto Sidechain nodes.

There is a need to sync container-related caching mechanism with the
actual Sidechain changes. To do this, node should be able to listen
incoming notifications about container ops.
Define `PutSuccess` / `DeleteSuccess` notification event's parsers.
Subscribe to these events in node app. As initial implementation node
will log event receipts. Later handling is going to be practically
complicated.

`Degraded` mode can be set by the administrator if needed.
Modifying operations in this mode can lead node into an inconsistent state
because metabase checks such as lock checking are not performed.

Do not check that a node indeed belongs to the container, because the
synchronization will fail in this case anyway.

Core changes:
* avoid package-colliding variable naming
* avoid using pointers to IDs where unnecessary
* avoid using `idSDK` import alias pattern

In previous implementation NeoFS CLI app used `network.Address.HostAddr`
as a server URI, which caused scheme loss since host address doesn't
contain it.
Rename `HostAddr` to `URIAddr` and make it to return URI address with
`grpcs` scheme if TLS is enabled. Make `TLSEnabled` unexported since it
was used to provide default `tls.Config` only (it is used by default in
SDK).

Morph "NewEpoch" event handling was registered in a closure over
`addNewEpochNotificationHandler` func. That may lead to the data race:
if a shard was initialized before the event registration, everything works
as planned, but if registration was made earlier, it was not able to
include GC handlers since a shard has not called `eventChanInit` yet and,
therefore, it has not registered handler yet.

In previous implementation `Container.Delete` operation caused local
node's cache invalidation (container itself, eACL and listings). Any
subsequent `Container.Get` operation reversed invalidation. Given the
low latency sensitivity of deleting a container, there is no need to
touch the cache. With this approach, all pending deletion operations on
the node via the NeoFS API protocol will be delayed by the cache TTL.
Do not call cache invalidation ops in `morphContainerWriter.Delete`.
Remove no longer needed `InvalidateContainerListByCID` and
`InvalidateContainer` methods.

Add worker pool to the listener to prevent blocking. It is used only for
notary notifications and new block events handling since it uses RPC
calls. That may lead to the deadlock state: neo-go cannot send RPC until
notification channel is read but notification channel cannot be read since
neo-go client cannot send RPC.

Updated client now supports subscription to chain notifications and RPC

GracefulStop() may be blocked until all server-side streams
are finished. There is no control over such streams yet, so
application may be frozen in shutdown stage.
Naive solution is to add timeout for GracefulStop(). At this
point healthy connection will be finished and unhealthy
connections will be terminated by Stop().
