the recovery action of "baremetal down" should be triggered mandatory

YARDSTICK-1222 has made attacker recover only when the sla not pass.
But for baremetal down test case, the node need to power on even the sla pass.

TODO:
Make attacker can support mandatory recover in some situation.

JIRA: YARDSTICK-1337
