nmcli: allow cmd specific option parsing in next_arg() func

Options dependant on specific commands (e.g., nmcli connection show
--active) are now allowed to be processed by the next_arg() function.
This would allow autocompletion to expand options belonging to specific
command first, and then global ones.

Note that global options ("--ask" and "--show-secrets") will be auto-completed
everywhere but only if at least a '-' is passed. Command specific ones
(--temporary, --active, --order) will be auto-completed only after the command
they belongs to but without requiring the user to pass a heading '-'.

Example:
'nmcli connection show -a'
will expand '-a' into '--active', but
'nmcli connection add -a`
will expand '-a' into '--ask' (as it is a global option)

This commit fixes also autocompletion for:
nmcli connection modify --temporary
