Why ignore chaos_os's response for ActionProcessHang exp creating

[spencercjh]

Issue Description

Type: bug report

Describe what happened (or what feature you want)

Why is the result of the experiment creation command ignored when model.ActionProcessHang = true in chaosblade/exec/os/executor.go#Exec? This leads to errors in related experiments (such as CPU, memory, disk load injection, file mutation experiments, etc.) not being returned to the user promptly, which makes the parameter validation before the actual execution of the experiments meaningless.

code:

https://github.com/chaosblade-io/chaosblade/blob/master/exec/os/executor.go#L71-L77

Here is an example:

The error is hidden in the log, and the outside world only ever gets 200, ok

Describe what you expected to happen

We should not treat model.ActionProcessHang differently. Ignoring the result of the experiment creation command when model.ActionProcessHang is true can lead to issues where errors are not properly reported, affecting the reliability and usability of the experiments.

How to reproduce it (as minimally and precisely as possible)

1. blade create file append --filepath=/home/logs/not-exist.txt
2. blade create disk burn --path /not-exist --read --size 10 --timeout 300 --write
3. ...
