Remove ScalarDB api dependency

[jnmt]

Description

This PR removes ScalarDB api dependency due to the following reasons.

• Client SDK now exposes the ScalarDB library, so we don't have to do it here.
• Potentially, it causes a version mismatch of libraries since ScalarDL (4.0.0-SNAPSHOT) uses a different ScalarDB version (e.g., 3.13.0 now).

Related issues and/or PRs

• Replace implementation with api #13

I guess we needed the dependency because ScalarDL Client SDK doesn't expose the ScalarDB library at that moment.

Changes made

• Remove ScalarDB api dependency.
