ea3d65ea - Fix eigenvalue parsing for compression-only quantize configs (#8057)

Fix eigenvalue parsing for compression-only quantize configs (#8057) ## Description This PR fixes eigenvalue configuration parsing in `deepspeed/runtime/config.py` for quantization-enabled configs. Previously, `get_eigenvalue_config()` assumed the legacy top-level `quantize_training` section always existed after `get_quantize_enabled()` returned true. That caused a `KeyError` for supported compression configs that enable weight quantization through `compression_training` without also defining `quantize_training`. This change makes the parser fall back to the default eigenvalue settings when the legacy section is absent, while preserving the existing behavior when `quantize_training` is present. ## Testing Added a regression test covering a `compression_training` weight-quantization config without a legacy `quantize_training` section. Validated locally with the repository's focused pre-commit checks. --------- Signed-off-by: Sowndappan S <147894621+sowndappan5@users.noreply.github.com> Signed-off-by: sowndappan5 <sowndappan610@gmail.com>
