ced854bc2e [#1175] object/fmt: Handle LOCK objects
Make `FormatValidator.ValidateContent` to verify payload of `LOCK`
objects. Pass locked objects to `Locker` interface. Require from
`Locker.Lock` to return `apistatus.IrregularObjectLock` error on a
corresponding condition.

Also add error return to `DeleteHandler.DeleteObjects` method. Require
from method to return `apistatus.ObjectLocked` error on a corresponding
condition. Adopt implementations.

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 '*'.
