This moves `hostName` to the `Collection` struct, where it's needed. The field is populated after successful `GetCollection...()` calls. This isn't the cleanest way to do things, but it accomplishes the goal. Eventually, we should accept the AppCfg to `GetCollection...()` calls, or make them `App` methods, instead of `datastore` methods. Ref T613
