> {*}Motivation{*}:
> We need to be able to use filters when data nodes are recalculated 
> *Definition of done:*
>  * Filters are applied when data nodes are recalculated 
> *Implementation details:*
> When we write data nodes to metastorage, we extend existing Map with data nodes and instead of saving only nodes' names, we store new structure called {{NodeWithAttributes}}, where we store name and attributes of the node. Currently, when we read data nodes, we convert existing map with node counters to a Set of nodes, which counters are more than 0. Now we also will apply filter, so as a result data nodes will be filtered with the according filter.
