Set flush mark in the inside the flush worker because writing to the blobstor
can fail. Because each evicted object must be deleted, it is reasonable
to do this in the evict callback.
The evict callback is protected by LRU mutex and thus potentially interferes
with `Get` and `Iterate` methods. This problem will be addressed in the
future.

If container listing cache on node's side is missing (for particular
owner), then updating it as a reaction to successful container creation
leads to potentially invalid cache value for a period of time equivalent
to cache TTL.
Immediately return from `ttlContainerLister.update` method if owner's
container list isn't cached.

From now cache TTL can be parameterized in the `neofs-node` app using
`cache_ttl` config key. `disable_cache` value is no longer supported.

In previous implementation storage node responded with the outdated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outdated responses node should update its cache on event receipts.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.

Maintain an invariant that any blobovnicza is present either
in `opened` or in `active` map. Otherwise, the logic becomes too
complicate because it is not obvious when we should close the blobovnicza.

This check should occur on the shard level, but because
blobstor components expose `Open(readOnly bool)` interface,
it is reasonable to expect an error here.

If the file doesn't exist, return `apistatus.ObjectNotFound`.
First check is still there as a shortcut.

This tests check that each blobstor component behaves similarly when
same methods are being used. It is intended to serve as a specification
for all future components.
