cloudctl machine ls shows two different kinds of output with conflicting template vars

[TLINDEN]

The command cloudctl machine ls $cluster shows 2 outputs: first the one of cloudctl cluster describe $cluster and then the actual machine status.

This is all fine and dandy unless you want to post-process the output using template vars. E.g.:

c cluster machine ls $cluster -o template --template "{{.Status.lastOperation.progress}} {{.hardware.cpu_cores}}"
Cluster:
100 <no value>

Machines:
<no value> 8
<no value> 24
<no value> 24
<no value> 24

Obviously the "describe cluster" output doesn't have a .hardware.cpu_cores and the "machine ls" output has no .Status.lastOperation.progress. Also the template I used here didn't mention Cluster: or Machines:, these headers had been printed directly and independently from the output type as it seems.

So, it would be nice to omit the "describe cluster" output with an option so that only the machine status list is being displayed. Or - maybe better - make this the default as the command name "cluster machine ls" suggests it anyway, and add an option to include the "describe cluster" output.
