There is a need to track the results of Object interactions with the remote
peers during node's lifetime. Each successful operation should increment the
number of satisfactory interactions with the remote peer, and the failed
ones, on the contrary, decrement. Collected numbers of satisfactory
interactions are going to be used for calculation of the normalized local
trust values according to original EigenTrust algorithm.

with the result of any object operation. The wrapper provides interface of
the remote client constructor. It is used as a `ClientConstructor` component

ttlNetCache should evict records after TTL duration. However if
data is often accessed and there are no LRU eviction (cache used

Solution is to not update access time on every get, so the data

Because options are not used when client is already in cache
providing them to shared cache is misleading at best.

Classifier looks at list of inner ring nodes and container
nodes from current and previous epoch to classify request.
Sometimes these checks might return error.
Consider there is a request from unknown key and container's
placement policy valid for current epoch and invalid for past
epoch. Classifier tries to find if key belongs to container
node from current epoch -- it is not. Then it tries to find if
key belongs to container node from past epoch and it throws
error, because placement policy is invalid for past epoch.
This is a legit case and classifier should ignore such errors
to provide best effort in matching. The only error classifier
should return is an error when request does not contain
public key to classify it.
