Recently there was the inclusion of remote config rollouts. Rollouts were introduced to the REST API documentation under the RemoveConfigParameterValue as seen here: https://firebase.google.com/docs/reference/remote-config/rest/v1/RemoteConfig#RemoteConfigParameterValue.

But the same isn't true for the Firebase-admin package https://firebase.google.com/docs/reference/admin/node/firebase-admin.remote-config.md#remoteconfigparametervalue.

Would be interesting to have the types that are now available under the rest api to also be available on server side libraries so the usage of rollouts wouldn't impact current implementations that make usage of firebase-admin
