first draft

fix build

fix ObjectInfo creation

another cleaned attempt

fix schema id cache population

correct splitting of URI into parts

tmp: lazy way to debug cluster

fix storage schema normalization

store per-file object_storage_ptr in object_info

tmp

upd

upd

fix for local

make new storages properly

remove cloneObjectStorage

attempt to fix cluster

use proper storage on worker's side + code cleanup

tmp

fix build after rebase

tmp

poke ci again
