Quality Evaluator - migrate the KPI Lib from v1.0 to v2.0

We need to migrate the current implementation from KPI Lib v1.0 to v2.0, which includes significant architectural changes. One of the key updates in v2.0 is the introduction of Python classes for each metric, replacing the previous functional approach.

KPI Lib v2.0 (based on Python classes) client example: https://gitlab.eclipse.org/eclipse-research-labs/datamite-project/data-quality/kpi-library/-/tree/feature/kpi_library_client/client?ref_type=heads
