Evgeny Khirin 7c30bc4301 [NOD-64] Remove subnetwork id supports all (#237)
* [NOD-64] Intermediate commit: need check tests on master

* [NOD-64] Commit before changing subnetwork IDS to new values

* [NOD-64] Fixed tests after changing subnetworks IDs constants

* [NOD-64] Extract duplicate code into functions

* [NOD-64] Renamed IsAllSubnetworks ==> IncludeAllSubnetworks
