Alex Vanin bca7cf9470 [] policer: Check context before job selection
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.
