Subject: [dovetail tool]check and get results for each cmd

JIRA: DOVETAIL-166

Check the results of each cmds executed in test case
1. the results of pre_condition, post_condition, cmds need to be checked,
   so it can get a quick fail, dont need to go through the next step
2. it's more accurate to show where error occurred as early as possible
3. get results from shell scripts
