Decouple store migration and core domain logic

[mabdh]

Is your feature request related to a problem? Please describe.
All domains have a Migrate() function that is being called by migrate command cli only. In this case, mixing migration logic in domain is not needed therefore it is not necessary to add Migrate to the service signature.
On the other hand, there is no business logic when running migration with migrate command. The migration should be store-specific and directly access repository layer.

Describe the solution you'd like

• Remove MigrateAll() function.
• Remove Migrate() function in all services.
• Update migrate command to run repository migration.
