license-check goal should log warn/error if review is needed.

Use WARNING level for log when review is needed.

[INFO] --- license-tool-plugin:0.0.1-SNAPSHOT:license-check (default-cli) @ leshan ---
[INFO] Querying Eclipse Foundation for license data for 21 items.
[INFO] Found 14 items.
[INFO] Querying ClearlyDefined for license data for 7 items.
[INFO] Found 7 items.
[WARNING] License information could not be automatically verified for the following content:

Use ERROR level for log when review is needed and failWhenReviewNeeded=true
