Implement a component that stores the values of the used space of
containers. The storage allows you to write several values for a fixed
container and epoch number, and read the averaged estimates of all
accumulated values. All values are stored in memory. This component is
planned to be used as an accumulator of opinions from various network
participants about the fullness of the container.

Implement a component that connects the value stores of the used space of
containers. Implement the Start/Stop operations on it, which will later
become the application handlers of the corresponding events from the
sidechain. The main task of the controller is to temporarily synchronize the
stages of calculating the global estimate of the used space in the
container. The details of the score calculation (the way of collecting /
transmitting local scores, the final score formula and writing to the
contract) are encapsulated in the dependency components, the controller is
abstracted from them.

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.

Support processing of NetmapEpoch and NetmapLookupDepth X-headers when
processing object read operations. Placement for operations
Get/Head/GetRange/GetRangeHash/Search is built for the epoch specified in
NetmapEpoch X-header (by default latest). Also the specified operations are
processed until success is achieved for network maps from the past up to
NetmapLookupDepth value. Behavior for default values (zero or missing) left
unchanged.

In previous implementation of eACL service v2 the response X-headers were
validated at the stage of re-checking eACL. This provoked a mismatch of
records in the eACL table with requests. Fix this behavior by checking the
headers from the request, not the response.

In previous implementation parent object header finalized twice in size
limiter + formatter. On the one hand, this added redundant action, on the
other hand, it could provoke a difference in the headers of the linking and
the last part. Change formatter to finalize parent header if it does not
container the signature. Change size limiter to reuse parent header after
last child finalization in linking child.
