Feature Request: Support Eclipse "Source Clean Up" actions

Eclipse provides a feature called Clean up (Right click a source folder: Source -> Clean Up). Clean up profile can be defined from
Preferences -> Java -> Code Style -> Clean Up. Clean up profiles can be exported to an xml file.

Like format settings, clean up settings could be set up with an xml file.

{
    "java.format.settings.url": "...",
    "java.cleanup.settings.url" : "..."
}

Also, I would like to contribute to this issue, if someone points me to the right direction.
