adding include-locales flag

Closes #127

I think it would also be a good idea if a generic list of args were to be specified as inputs, that way we won't have to release a new version of the plugin when new arguments are added to jlink.

@aalmiray but how many args are there? There are only a few of them which means it's better to give per-arg change that makes every one of them much easier to validate.

That is the thing, its a generic way to pass arbitrary args to jlink. It’s the developer’s responsibility to set these args with the correct format and settings, no validation will be performed.

Validation may only be performed with explicit args. Now, if you run jlink —help you see a handful of arguments that could be explicitly mapped to plugin args. The one you are requesting belongs to a jlink plugin. The question is, is this plugin always active?

What happens if someone requests a plugin arg and said plugin is not active by default? Or are all plugins always active?

@aalmiray okay, fair enough. I can update this PR just to introduce an all-purpose generic-style plugin argument.
