// TestClientLive is a smoke test against a real OpenStack deployment. It's
// skipped unless OPENSTACK_LIVE_TEST=1 and the usual OS_* credential env
// vars are set, so the default `go test ./...` run needs no cloud access.
// It only exercises GetFloatingIPByAddress (read-only) against
// OS_TEST_FLOATING_IP, to avoid mutating real infrastructure in CI.
//
// OS_AUTH_METHOD selects which credential shape to test: "token" (default)
// reads OS_TOKEN and exercises the passthrough path; "password" reads
// OS_USERNAME/OS_PASSWORD/OS_USER_DOMAIN_NAME and exercises the
// auto-obtain/auto-reauth path. Run once per method to validate both
// against the real deployment.
