fix oozie ssh action bug:
executing a not exists command in ssh action would be success rather than fail.
it's caused by:
1. WorkflowJobBean.run is set to 0 while start action.
2. WorkflowJobBean.run is init to 1 while check action status. (this patch change the 1 to 0.)
3. WorkflowJobBean.run is part of ActionExecutorContext.recoveryId.
4. SshActionExecutor check command result status by the file existence of ${ActionExecutorContext.recoveryId}.error.
