Changing database scheme

Change src/iden.rs.
Create new migration under src/m20220101_00000XX_create_table.rs.
Add the migration in src/lib.rs.
Apply migration (on postgres, sqlite will give wrong types in the autogenerated entities, application by cargo run in migration directory may fail, while running the whole kellnr succeeds).
Generate new entities running sea-orm-cli generate entity -u postgresql://admin:admin@127.0.0.1/kellnr_dbpostgresql://admin:admin@127.0.0.1/kellnr_db (adjust this command appropriately) in the src/m20220101_00000XX_create_table_entities directory.
Copy entities to ../entity/src (mod.rs shall go to lib.rs).
