Description

Currently, Java client internally uses a public API to execute sql queries (and some tests also rely on this fact).
In order to pass the observable timestamp to the sql engine and keep the code clean, we need to switch to using the internal API and rework the related tests.
This must be done after the completion of IGNITE-19898.
