nmcli: improve handling nicks for enum values

Browse source 
For enum type properties, we support to specify a list of
aliases.

- the getter uses a separate list from the setter. The idea
  is that some of these aliases are only for showing, but not
  for setting. Add a special marker GOBJECT_ENUM_VALUE_INFOS_GET_FROM_SETTER
  which indicates that the value information from the setter
  should also be used by the getter.

- extend _values_fcn_gobject_enum() to also return the nicks from
  the setter for bash completion. After all, they can be set too.
