When org. units group_by is applied, UI should display the suborgs/accounts below the specified org. unit.

Example using cost_aws_org_unit_crud_source fixture (data can be loaded into ci env upon request):

Root org. unit id QE_R_001 (alias QE Root) has 2 suborgs and 1 account (see org_unit_hierarchy.png and org_unit_api.png):

• org. unit id QE_OU_001, alias Dept QE_OU_001 (Rename)
• org. unit id QE_OU_002, alias Dept QE_OU_002
• account id 8888888888880, alias QE Root A Test

When group_by[org. unit] = "QE Root" is applied in UI, it shows only one item "Dept QE_OU_002 (id QE_OU_001)" instead of 3 expected items (see org_units.png)

Api calls used in example:

/api/cost-management/v1/reports/aws/costs/?filter[time_scope_units]=month&filter[time_scope_value]=-1&filter[resolution]=monthly&group_by[org_unit_id]=QE_R_001

/api/cost-management/v1/organizations/aws/?filter[time_scope_units]=month&filter[time_scope_value]=-1&filter[resolution]=monthly

UI api call:

/api/cost-management/v1/reports/aws/costs/?delta=cost&filter[limit]=10&filter[offset]=0&filter[resolution]=monthly&filter[time_scope_units]=month&filter[time_scope_value]=-1&group_by[org_unit_id]=QE_R_001&order_by[cost]=desc
