kubernetes: always use lb for joining

Browse source 
The token given out by control-planes contains the node IP
as an endpoint. Since during this stage the joining node is
not connected to the WireGuard network, we cannot
communicate node-to-node. Therefore, we need to hop over the
load balancer again to have a src IP outside of the strict
range.
