Add a live-test script

This can be used to test that all the existing commands work correctly. It
needs a running cluster with at least one instance to run all the tests.

+# cluster via ssh and an exported LUXI interface (via socat, for

+# enough. If running remotely, set env vars as follows: LUXI to the

+# used to login on the cluster (e.g. CLUSTER="ssh root@cluster").
