I guess as simple as this:

import java.util.List;

import org.alfresco.repo.action.executer.ActionExecuterAbstractBase;
import org.alfresco.service.cmr.action.Action;
import org.alfresco.service.cmr.action.ParameterDefinition;
import org.alfresco.service.cmr.repository.NodeRef;
import org.alfresco.service.cmr.version.VersionService;

public class DeleteVersionHistoryActionExecuter extends ActionExecuterAbstractBase{

    private VersionService versionService;

    @Override
    protected void executeImpl(Action action, NodeRef actionedUponNodeRef) {
        versionService.deleteVersionHistory(actionedUponNodeRef);

    }

    @Override
    protected void addParameterDefinitions(List<ParameterDefinition> paramList) {
        // TODO Auto-generated method stub

    }

    public void setVersionService(VersionService versionService) {
        this.versionService = versionService;
    }
}

And define the ActionExecuter in a *.context.xml file

<?xml version='1.0' encoding='UTF-8'?>

<bean name="deleteVersionHistoryAction" class="com.your.package.DeleteVersionHistoryActionExecuter" parent="action-executer">
    <property name="versionService" ref="versionService" />
</bean>

Now restart your Alfresco, you can now use your ActionExecter. With the runas functionality, or defining a rule on a folder, where the action gets triggerd.

The VersionService provides both deleteVersion and deleteVersionHistory. There's currently no way to access such methods via Javascript, so you need to code some Java. I'd suggest you to write a custom Java Action that calls such methods.
