We use cache to avoid policing the same object multiple times in a short
time span (< 30 seconds). If we have 200_000 objects in a blobstor, it is a bit useless
-- if it takes 1 second to process an object and we have `replicator.pool_size: 20`
in config, the next iteration will happen in 10_000 second which is much
larger than 30 second. However we still consume a lot of memory, so it
makes sense to use saner default.

Includes extending listing methods in the Storage Engine with object types.
It allows tuning replication/policer algorithms: container nodes do
not remove `LOCK` objects as redundant and try to fulfill `LOCK` placement
on the ohter container nodes.

Node response with `NODE_UNDER_MAINTENANCE` status signals that the node
was switched to maintenance mode. There is a delay between the actual
switch and the reflection in the network map of up to one epoch. To
speed up the reaction to the maintenance, it is required to recognize
such node responses in the Policer.
Make `Policer.processNodes` to exclude elements with shortage decreasing
on `NODE_UNDER_MAINTENANCE` status response.

Nodes under maintenance SHOULD not respond to object requests. Based on
this, storage node's Policer SHOULD consider such nodes as problem ones.
However, to prevent spam with the new replicas, on the contrary, Policer
should consider them normal.
Make `Policer.processNodes` to exclude elements if `IsMaintenance()`
with shortage decreasing.

Cache object that are being processed. That prevents concurrent
object handling when there is a few number of objects and object handling
takes more time that the policer needs for starting that object handling one
more time.

If placement contains two vectors with intersecting nodes it was possible to
send the object to the nodes twice.
Also optimizes requests: do not ask about storing the object twice from the
same node.

When application is being terminated, replicator routine
might be on the object picking phase. Storage is terminated
asynchronously, thus `Select()` may return corresponding
error. If we don't process `context.Done()` in this case,
then application freezes on shutdown.

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 of Policer's job queue the same list of objects for
