GO-3974: support kanban view based on relations with object format

[AnastasiaShemyakinskaya]

Add support for kanban based on relation with objects types

1. Firstly, we try to get ObjectType list from relation, so we can figure out object types of needed objects
2. We try to query objects with received object types, it would be out columns in kanban
3. We try to query objects with given relation, because some objects can contain 2 and more objects inside relations. So we can build columns in kanban, which represents such cases
