1. Remove `common/quota` package. 2. Remove functions about quota in `common/dao` package. 3. Move `Quota` and `QuotaUsage` models from `common/models` to `pkg/quota/dao`. 4. Add `Count` and `List` methods to `quota.Controller`. 5. Use `quota.Controller` to implement quota APIs. Signed-off-by: He Weiwei <hweiwei@vmware.com>
