Improve CLI output for complex commands

Browse Source 
Complex commands may have many options or non-standard output. This
patch adds 2 improvements to handle these commands better:
  1) Add "option_group" parameter attribute
     Make command help more readable by specifying an option group
     for the parameter. All parameters in the same option group are
     then placed to one named option group
  2) Allow nested entries in the output
     Current CLI output module cannot handle a list of nested entries
     (dictionaries) contained in an entry attribute. Make sure they
     are printed properly (with indentation)
