Description

### Search before asking

- [x] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement.

### Description

I noticed that if user try to kill the task/process, for example, a Java task, dophin scheduler will send "kill -9" which is "SIGKILL" signal to java worker process.

Would you please make the kill signal be configable? Becasue in some situation, we want worker process to send "I am killed" message to specific observer application or do something else to clean resource when user try to kill task/process via dophin scheduler. And if the worker process is killed by ""SIGKILL" signal, there is no chance for "JVM runtime hook" to do something when the process needed to exit.

Thererfore, would you please make the kill signal be configable? Thanks for your help.

### Use case

User can be config the kill signal type of specific work process/task.
