Subject: [PATCH] Change db_migrator major version on master branch from
 version 2 to 3 (#2272)

To add room for db_migrator changes in 202012 branch, changed the major version on master/202205 branches from "2" to "3"

This change is needed:
1. Since the existing master/202205 db versions cannot be backported to 202012 as they are not relevant to 202012.
Current latest DB version for 202012 is 2_0_0, to add newer versions 2_0_1 cannot be added as it is already used for master/202205 branch.
2. Since master/202205 branches should incremented major version that was reserved for 202012. Since 202205 used same major version as 202012, there is no place for migrator changes to go into 202012 branch.

Changed major version on migrator script. Updated test files.
