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 the previous implementation of the metabase, there was no possibility of

There is a need to limit disk space used by write-cache. It is almost
impossible to calculate the value exactly. It is proposed to estimate the
size of the cache by the number of objects stored in it.
Track amounts of objects saved in DB and FSTree separately. To do this,
`ObjectCounters` interface is defined. It is generalized to a store of
numbers that can be made persistent (new option `WithObjectCounters`). By
default DB number is calculated as key number in default bucket, and FS
number is set same to DB since it is currently hard to read the actual value
from `FSTree` instance. Each PUT/DELETE operation to DB or FS
increases/decreases corresponding counter. Before each PUT op an overflow
check is performed with the following formula for evaluating the occupied
space: `NumDB * MaxDBSize + NumFS * MaxFSSize`. If next PUT can cause
write-cache overflow, object is written to the main storage.
By default maximum write-cache size is set to 1GB.

There is a need to work with a set of Neo RPC nodes in order not to depend

NeoFS network dictates the limitation of the maximum size of the "finished"
objects. The payload size of an object is recorded in its header. When
writing finished objects, the nodes must check:
* satisfying the constraint;
* matching the value in the header to the number of payload bytes.
Provide value returned by `MaxSizeSource` component to `validatingTarget`.
Check max size value during the stream of the "finished" objects. Check
header value during the streaming and on-close. Check payload size in v2
relay scenario.

Session token can be presented `Put`, `Delete` and `SetEACL` notification
events. IR should consider this case as issuing a power of attorney to a
third party. Thus, checking the eligibility for an operation should be
complicated:
- token owner should be the owner of the related container;
- the intent must be signed with a session key;
- the power of attorney must be signed by the owner of the container.
Omitted checks (TBD):
- session token should have container session context;
- the verb of the context should correspond to the operation.
