Is your feature request related to a problem? Please describe.

To support async truncation on es sink for https://github.com/risingwavelabs/risingwave/issues/17095, it's better to reimplement es sink with rust sdk, which provides async functionality.

Currently, though data is written with java sdk, the json index is already built with rust code, so there should not involve too much work of extra development.
