Introduce new storage component Peapod

Currently, storage node saves relatively small NeoFS objects in Blobovnicza tree component: group of BoltDB wrappers managed as a tree. This component has pretty complex data structure, code implementation and dubious performance results. Peapod is a new storage component introduced to replace Blobovnicza one as more simple and effective. It also bases on single BoltDB instance, but organizes batch writes in a specific way. In future, Peapod is going to be used as a storage of small objects by the BlobStor. Refs nspcc-dev#2453. Signed-off-by: Leonard Lyubich <[email protected]>
