Feature Request: Allow execution of folders in order given on the command line

[mklinger]

Folders can be specified on the command-line and only the specified folders will be executed from the collection. The order in which the folders are executed is defined by the collection and cannot be changed.

The underlying Postman executor allows specifying the preserveOrder flag. When this flag is enabled, the execution order is defined by the order of the folders given, instead of the order in the collection.

It would be nice, if Newman could offer a command-line option to enable this behavior.
