cli: add new style for tokenizing/concatenating list options in nmcli

Browse source 
nmcli supports list options (optlist and multilist properties).
These commonly are individual items, concatenated by a delimiter.

It should be generally possibly to express every value. That means, we
need some for of escaping mechanism for delimiters.

Currently this is all inconsistent or no escaping is supported. I intend
to fix that (which will be a change in behavior).

For now, just add yet another style of tokenzing/concatenating list
items in nmcli. This is the style to replace all other styles.
