This patch changes logic from counting all nodes to counting only read-write nodes when messaging about DML operations. feat(MCOL-6082): Multiple readers of dbroots using OamCache logic This patch introduces centralized logic of selecting what dbroot is accessible in PrimProc on what node. The logic is in OamCache for time being and can be moved later. Fix build
