We're unable to configure a debezium source whitelists via environment variables. or example, when passing the env variable:

DEBEZIUM_SOURCE_TABLE_WHITELIST=public.table_name

It is not picked up by the underlying connector. However "debezium.source.table.whitelist" as an environment variable works (however "." is not allowed in env variable names on linux).

I think the issue is with this code. "getPropertyNames()" returns the non-normalized property names. For example when passing the "DEBEZIUM_SOURCE_TABLE_WHITELIST" it returns "DEBEZIUM_SOURCE_TABLE_WHITELIST" when I assume it's expecting it to be normalized to "debezium.source.table.whitelist".
