[#1175] CLI: Implement command to lock the objects

Implement `lock` command and add it to `object` section. The command
accepts container argument (string `cid.ID`) and list of locked objects
(string `oid.ID` list). From the provided input `LOCK` object is
constructed and stored using NeoFS API protocol.
