Bare metal node N+1 redundancy

Registered by Nguyen Hung Phuong on 2018-09-05

This proposes high availability/reliability feature to support Bare Metal Node N+1 Redundancy based on data from Ceilometer.

When a bare metal node is failed due to hardware problem or is likely to be failed due to a sign of hardware failure, this function allows to switch over the node safely to another bare metal node in short time if the failed node is booted from a volume.

Overall idea can be found in the following presentation slides P.60 - P.63.
