Display host lists as regrouped ClusterShell nodesets

[degremont]

Automatically display host lists as regrouped ClusterShell nodesets when possible. Add a command line option to disable that behavior.

Eg.
# shine status -n @rack1
=== FILESYSTEM STATUS (fs) ===
TYPE # STATUS NODES
---- - ------ -----
CLI 38 mounted @rack1

Thanks for the patch. I like the idea.

I'm only concern about performances considerations as regroup could be expensive in some configurations. It will probably require some improvements. Instead of using "noregroup=False", use "regroup=True".
I'm thinking about an option in shine.conf to control the default behaviour. Something like how color behaves. Controling the group source used when regrouping could be interesting too.

Doing regroup=True was my first approach. Except I didn't find a good argument to justify adding an option to every shine command I type. :) So I made it the default display, with an option to disable it.

Having an option in shine.conf sounds like a good solution too.
