[Feature Request]: Add watchdog / auto kill functionality to "Execute a Process" actions.

### What would you like to happen?

Many times when functionality is limited within Hop it is useful to execute a process that carries out the tasks and then returns. Problems arise when the process hangs or never finishes. I would like to request some kind of traditional watchdog timer / parameterization that would automatically kill the process if it takes to long or never occurs so my pipelines and workflows can eventually finish.

### Issue Priority

Priority: 3

### Issue Component

Component: Transforms

The issue concerns the "Execute a Process" actions in Hop transforms. Start by locating that action and how it currently handles processes that hang; define the timeout and termination behavior, then verify that a pipeline can finish when the process exceeds the configured limit.
