Test manual

marketplace-aws to standard

Switching marketplace-aws to standard for local instance:

$ curl -H $AUTH "http://localhost:8000/api/rhacs/v1/admin/centrals/cml530p8pthd6k6u5i50/billing-model" \
-X PATCH \
-d '{"model": "standard", "cloud_provider": "aws", "cloud_account_id": "676188018476"}'
$

Resulting quota_cost:

    {
      "allowed": 25,
      "consumed": 1,
      "href": "/api/accounts_mgmt/v1/organizations/2D58jWME1XKVfAl0h3MGH5eekmc/quota_cost",
      "kind": "QuotaCost",
      "organization_id": "2D58jWME1XKVfAl0h3MGH5eekmc",
      "quota_id": "cluster|rhinfra|rhacs|standard",
      "version": "4d479bfc-8be3-4f16-817b-67220f124b21"
    },
    {
      "allowed": 50,
      "consumed": 6,
      "href": "/api/accounts_mgmt/v1/organizations/2D58jWME1XKVfAl0h3MGH5eekmc/quota_cost",
      "kind": "QuotaCost",
      "organization_id": "2D58jWME1XKVfAl0h3MGH5eekmc",
      "quota_id": "cluster|rhinfra|rhacs|marketplace",
      "version": "4d479bfc-8be3-4f16-817b-67220f124b21"
    },

Changing back to marketplace-aws transfers the quota back.
