When attributes were specified with an incorrect noderange
it was failing to report the noderange error. If that were
specifically addressed, it would then proceed to erroneously
complain about valid attribute names.
nodelist command would show 'help' with no arguments, but
natural expectation is to list all nodes. Adjust to match
that expectation. If a noderange was somehow problematic,
the output was not appropriate, this too is addressed.
nodeconsole provides a wrapper for confetty offering logical
tab completion for console specifically as well as help
text to explain critical info about using nodeconsole.
nodelist provides functionality analagous to nodels in
xCAT 2.x codebase
