### Search before asking - [X] I had searched in the [feature](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement. ### Description We had supported default value with el expression feature in [sink-options-placeholders](https://seatunnel.apache.org/docs/concept/sink-options-placeholders). We should support default value with el expression in all config place too. Including `env`, `source`, `transform`, `sink`. It's a sub feature of [config-variable-substitution](https://seatunnel.apache.org/docs/concept/config#config-variable-substitution). So the el expression with default value will be replaced with user configure value when use shell script with `-i`. PS: we should replace all variables's default value (which not be replaced by `-i`) in `TableFactoryContext` constructor so that our web also can use default value feature.
