Hi.
To keep the type of an event when it is cloned, I wantet to use
```
clone { clones => ["%{type}_cloned"] }
```
and end up with an type `%{type}_cloned` instead of `my_type_cloned`.
Is this a bug or a feature?
You can try this config to repoduce it on the command line:
```
-e 'filter { clone { clones => ["foo_%{host}"] add_tag => "%{host}"} }'
```
The tags should contain your hostname while the type stays `foo_%{host}`.
How can I keep the type even in cloned events? Tagging it is good enough for me.
