Leonard Lyubich 9508633a7e [#1175] metabase: Work with LOCK objects
After introduction of LOCK objects (of type `TypeLock`) complicated
extended its behavior:
  * create `lockers` container bucket (LCB) during PUT;
  * remove object from LCB during DELETE;
  * look up object in LCB during EXISTS;
  * get object from LCB during GET;
  * list objects from LCB during LIST with cursor;
  * select objects from LCB during SELECT with '*'.
