E2E: Use kind cluster for clusterctl upgrade tests

This enables the UseKindForManagementCluster flag for all clusterctl
upgrade tests, which makes them use a kind cluster as the secondary
management cluster instead of creating an OpenStack workload cluster.

This significantly reduces the resource requirements for these tests
by using lightweight kind containers instead of full VMs, and it also
speeds up the test execution.
