option_parser: Extend option parsing for lists

Browse Source 
While parsing each parameter for getting the list of option/value, we
check if the value is a list separated between brackets. If that's the
case, we reconstruct the list so that it can be parsed afterwards, even
though it uses commas for separating each value.
