**Description**
Add timeout feature for each benchmark.

**Major Revision**
- Add `timeout` config for each benchmark. In current config files, only set the timeout for kernel-launch as example. Other benchmarks can be set in the future.
- Set the timeout config for `ansible_runner.run()`. Runner will get the return code 254:
   [ansible.py:80][WARNING] Run failed, return code 254.
- Using `timeout` command to terminate the client process.
