class PluginBase(vaping.io.Thread):

    - config (`dict`): plugin config
    - vaping: reference to the main vaping object

    Calls `self.init()` prefork while loading all modules, init() should
    not do anything active, any files opened may be closed when it forks.

    Plugins should prefer `init()` to `__init__()` to ensure the class is
    completely done initializing.

    Calls `self.on_start()` and `self.on_stop()` before and after running in
    case any connections need to be created or cleaned up.
