Public bug reported:

There are patterns like

    @property
    def core_plugin(self):
        try:
            return self._core_plugin
        except AttributeError:
            self._core_plugin = manager.NeutronManager.get_plugin()
            return self._core_plugin

There are issues.
- NeutronManager.get_plugin already cached it. No need to cache again.
- each class implements its own way(with or without cache), various name.

The caching should be removed and their implementation should be unified
