fix(ssh): Modify the return type of execWithPwd to include the output content

Adjust the return type of the `execWithPwd` method to `(int?, String)` so that it can simultaneously return the exit code and output content

Fix the issue in ContainerNotifier where the return result of execWithPwd is not handled correctly

Ensure that server operations (shutdown/restart/suspend) are correctly pending until the command execution is completed
