error: syntax error at "--storage-logical_unit-address", see help on collection based arguments for more details

this bug caused by incorrect parameter representation in RSDL,
storage-logical_unit [1] implemented as collection while RSDL 
reporting it as Type

[1]

    public List<LogicalUnit> getLogicalUnits() {
        if (logicalUnits == null) {
            logicalUnits = new ArrayList<LogicalUnit>();
        }
        return this.logicalUnits;
    }

my bad, - (was on old branch), current RSDL impl is correct (see cli help [1]), usage is not, Elena please always review /help/ to determinate correct option format.
