Rewrite the HA test case (2)

idea: refact the Monitor class in old file "monitor.py" with the base
class and sub-class.
detail:
1) the BaseMonitor is the base class of other monitor
2) each monitor run in independent process
3) there are two monitor("openstack-cmd" and "process") for the first test case
4) MonitorMgr class used to manager monitor process
