clush: simplify the noderange printed

[thiell]

Hello,

Clusters often end in messy states that requires to run commands on a noderange full of holes like:

fortoy[200-203,205-233,235-345,347-500,...]

It could be nice to introduce an option that optimize the noderange printed as result, using groups and exclusion. For instance with the above example:

@compute -x fortoy[204,234,346]

[st-cea] This solution is being investigated. But correct syntax of simplified displayed nodeset would be:

@compute!fortoy[204,234,346]
