We remove the SSH access from anywhere for the cluster VMs by updating the `all_machines` security group to only allow SSH from other machines in the `all_machines` security group. This PR requires appuio/terraform-modules#51 in order to ensure that the LBs remain accessible from anywhere via SSH and can act as SSH jumphosts for SSH access to the cluster VMs.

Note that when defining security group rules with another (or the same security group) as source there's no need for separate rules for IPv4 and IPv6.
