Bin Qian 133da10b08 split-brain avoidance improvement
This change enables one way communication via BMC (if configured)
through mtce.
when 2 controllers lost all communications to each other.
The algorithm is:
when communications all lost,
both active and standby controllers, verify its interfaces (mgmt,
infra, and oam)
if active controller is healthy, it will request a bmc reset
thorugh mtce, against standby controller.
if standby controller is healthy, it will active itself and wait
a total 45 seconds before requesting a bmc reset through mtce,
against the active controller.

Changes also include:
1. adding new initial failover state.
   initial state is a state before the node is enabled
2. remove failover thread.
   using worker thread action to perform time consuming operations
3. remove entire failover action table
