Passing non-related arguments breaks the codes

https://github.com/jina-ai/executor-simpleindexer/blob/3a5017b4c71c09fc6209aa04412815f1f1896a16/executor.py#L59

This line requires all the parameters must be acceptable by `.match()`, which does not hold in general.

```
f = Flow().add(uses='jinahub://SimpleIndexer')
with f:
f.post(on='/search', parameters={'foo': 1})
```

`.match()` does not accept unknown arguments,
