When restoring a snapshot to a new cluster, users may expect the cluster
to not contain any conflicting indices or data streams. However, some
features, such as the GeoIP processor, automatically create indices at
startup.
This adds and updates related procedures in the restore a snapshot tutorial.
I plan to improve other documentation related to feature states in snapshots
in a separate PR(s).
This PR also updates the restore snapshot API's example to include
the `indices` and `feature_states` parameters.
