Apply allowlist to the resource group query

### What Operating System(s) are you seeing this problem on?

Linux (x86-64)

### Backend.AI version

2ece7bf

### Describe the bug

Resource group is accessible by white list basis, and if it is specified in one of domain, project, and/or keypair policies, users belonging to the hierarchical layer can access the resource group. But when I query with `scaling_groups_for_user_group` (gql), only resource groups that belong to the project are shown even if I allowed that resource group to the domain.

Let's apply white list to the resource group gql query too.

### To Reproduce

Set allowed resource groups only for keypairs or domains and query `scaling_groups_for_user_group`.

### Expected Behavior

include keypair, domain resource groups

### Anything else?
