Pavel Pereslegin updated IGNITE-18699:
--------------------------------------
Description:
Currently {{ColocationGroup}} stores "assigments" in a "2-dimensional" list
(List of Lists).
Each element of which corresponds the partition number and stores nodes list
(assignment).
The first node in this list is the primary node (replica) for the partition,
the others are backup/secondary node (replica).
But production code only works with the primary replica, so it seems that we
can simplify the implementation and replace the "2 dimensional" list with a
simple list with primary replicas.
