> {*}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:*
> After the parsing phase, the expression can be converted to a condition for the filter from the Java Stream API. This filtering can be performed on a set of nodes’ attributes. This set could be retrieved from the CMG, we just need consistentIds of nodes.
> After that we need to use this filter when we write data nodes to metastore, there are few places, where we do that
> * {{DistributionZoneManager#saveDataNodesToMetaStorageOnScaleUp}}
> * {{DistributionZoneManager#saveDataNodesToMetaStorageOnScaleDown}}
> * {{DistributionZoneManager#saveDataNodesAndUpdateTriggerKeysInMetaStorage}}
