Add alternative usage for the configuration that contains "blacklist/whitelist" terminology

[tlfeng]

Is your feature request related to a problem? Please describe.
Replace "blacklist/whitelist" terminology in configurations, where the backwards compatibility will be impacted.

A part of #1483

Describe the solution you'd like

1. Replace the old usages that having "blacklist/whitelist" in configurations with "denylist/allowlist", then create duplicate usages with the old terminology for backwards compatibility (including fallback logic to fallback to settings with the new name).
2. Add tests to check both old and new usages of the configurations.
3. Add proper deprecation notice to the old usages.

Describe alternatives you've considered
None.
