With neo-project/neo-modules#358 nodes support RPC to
return used magic number. Therefore client doesn't need
that configuration value any more.

Neo-go does not use smartcontract.Parameter to return values
anymore, so it's convertes partly removed from neofs-node.

There is an optimization to send ApprovePeer tx only in
case if `touch` returns false. It returns false if node
is not in the cache or it was flagged to removal.

This event will be produced by new epoch handler. All
cleanups should be synchronous because smart contract can't
store inner ring votes forever. Therefore voting should be done
in similar time interval for all inner ring nodes.

Cleanup table is a cache for inner ring node to look for netmap
snapshot. It updates access time of bootstrapped nodes and will
be used to send `updateState` txs to clean netmap from unresponsive
nodes.

Implement Replicator service that performs background work to replicate
local object to remote nodes in the container. Replicator is going to be

There is a bit to allow or deny bearer token check for
each object service method. If this bit is not set then
ignore bearer token and use extended ACL table from
sidechain.

If bearer token is presented in the request then check
if it is a valid one and then use it to process extended
ACL checks.

Malicious user can stole public session key and use
it by sending request from it's own scope. To prevent
this each session token is signed and signature private
key must be corresponded with owner id in token. Therefore
malicious node cannot impersonate request without private
key to sign token.

Implement Policer service that performs background work to check compliance
with the placement policy for local objects in the container. In the initial
implementation, the selection of the working queue of objects is
simplified, and there is no transfer of the result to the replicator.

In #37 we've decided to remove length check, because smart contract would
fail on casting `nil` value from storage to `[]byte` producing FAULT state.
Apparently it does not fail, so we have to check length explicitly.

Classifier fetches public key of the request owner
and owner itself. Extended ACL check should rely on
this public key, because it might be extracted from
