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. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
