This change is aimed to reduce DSM overhead by using a lightweight object instead of linked maps.

Introduced DataStreamsTags and DataStreamsTagsBuild which are now used instead of LinkedHashMap.
Updated all integrations and tests.

My tests show ~10% throughput increase with a significant latency decrease without increasing CPU load.
