Fix usage ping misreporting consolidated object storage settings

When consolidated object storage settings are in use, we internally
modify `Settings` for all the object store types. However,
`Settingslogic` currently assumes the data loaded from a YAML is fixed,
so internally it stores data both as a Hash but also defines an accessor
that wraps each key. This results in two different objects that store
the same data. For example, with CI artifacts:

```
(byebug) Settings.artifacts.object_id
=> 233940
(byebug) Settings['artifacts'].object_id
=> 233960
(byebug) Settings['artifacts'].class
Hash
(byebug) Settings.artifacts.class
Settings
```

Our uploaders use the `Settings.artifacts` format, but the usage ping
uses `Settings['artifacts']`. Both should be equivalent, so we make them
consistent by having consolidated object storage parser assign both.
