Subject: [PATCH] local-up-cluster.sh: install CSI snapshotter

This cluster add-on is required for snapshotting of CSI volumes and
must be installed when bringing up a cluster because CSI driver
installations depend on that.

It is unclear how many users of the script need CSI snapshotting,
therefore it is disabled by default (= the previous behavior).
