Currently to find a node by path we iterate over all the children on each level. This is far from optimal and scales badly with the number of nodes on a single level. Thus we introduce "indexed attributes" for which an additional information is stored and which can be use in `*ByPath` operations. Currently this set only includes `FileName` attribute but this may change in future. Signed-off-by: Evgenii Stratonikov <evgeniy@nspcc.ru>
