Parallel progress output shows `master-0`/`worker-0` for all lines

[eliasp]

The parallel progress bar which shows the progress of the individual servers after creating them shows the name …master-0/…worker-0 for all shown lines instead of the correct names, e.g.:

...k8s-e336-master-0 : complete!                         100.0% [==============]
...k8s-e336-master-0 : complete!                         100.0% [==============]
...k8s-e336-master-0 : complete!                         100.0% [==============]
...k8s-e336-worker-0 : rewrite kubeconfigs                58.3% [=======>------]
...k8s-e336-worker-0 : deploy load balancer               41.7% [====>---------]
...k8s-e336-worker-0 : deploy load balancer               41.7% [====>---------]
...k8s-e336-worker-0 : deploy load balancer               41.7% [====>---------]
...k8s-e336-worker-0 : deploy load balancer               41.7% [====>---------]

It should look instead like this:

...k8s-e336-master-0 : complete!                         100.0% [==============]
...k8s-e336-master-1 : complete!                         100.0% [==============]
...k8s-e336-master-2 : complete!                         100.0% [==============]
...k8s-e336-worker-0 : rewrite kubeconfigs                58.3% [=======>------]
...k8s-e336-worker-1 : deploy load balancer               41.7% [====>---------]
...k8s-e336-worker-2 : deploy load balancer               41.7% [====>---------]
...k8s-e336-worker-3 : deploy load balancer               41.7% [====>---------]
...k8s-e336-worker-4 : deploy load balancer               41.7% [====>---------]
