Handle connection profiles in a single 'show' command instead of 'show active'
and 'show configured'.

nmcli con show [--active] [[id|uuid|path|apath] <bla>]

nmcli con show           : display all connection profiles
nmcli con show --active  : only display active connection profiles
                           (filters out inactive profiles)

nmcli con show myeth     : display details of "myeth" profile, and also active
                           connection info (if the profile is active)
nmcli -f profile con show myeth : only display "myeth"'s static configuration
nmcli -f active  con show myeth : only display active details of "myeth"
nmcli -f connection.id,ipv4,general con show myeth
                                          : display "connection.id"a property
                                            "ipv4" setting and "GENERAL" group
                                            of active data
