### Search before asking - [X] I had searched in the [DSIP](https://github.com/apache/dolphinscheduler/issues/14102) and found no similar DSIP. ### Motivation Now we support 2 kinds of parameter definition. 1. System variable use `${}` 2. Time related variable use `$[]`, and in this variable we also support data calculate, like `$[add_months(yyyyMMdd,N)]` But now we can't support the case that we need concat a fixed value with a dynamic value. like `/tmp/${system.workflow.instance.id}` Do we need improve the parser to support more flexible definition. like `/tmp/$[yyyy-MM-dd]/${system.workflow.instance.id}` ### Design Detail  refactor the current class, make each class's function clear create 3 parser implemention - InnerSystemParser find the `${}` variable, and replace with parameterMap's value - TimeParser find the `$[]` variable, calculate and replace time related placeholder - StringParser find the `$<>` variable, and for loop to find other placeholder, `${}`, `$[]`. replace the response with placeholder. ### Compatibility, Deprecation, and Migration Plan _No response_ ### Test Plan Create new test and update/check exist test ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
