[Improvement] Support restartTrigger

[sophon-zt]

Current implementation:
If the "reloadAction" is defined, execute this reloadAction to implement configuration changes.
If the "reloadAction" isn't defined, the pod will be restarted to implement the configuration change.

The "autoTrigger" seems rather redundant as it defines a autoTrigger to tell the operator that nothing needs to be done.

A better approach:
Define a "restartTrigger" which tells the operator to implement the reload by restarting. If the "reloadAction" isn't defined, the operator doesn't need to do anything.
