Doc Text:
This enhancement adds the ability to automatically reschedule load balancers from LBaaS agents that the server detects as dead. Previously, load balancers could be scheduled and realized across multiple LBaaS agents, however if a hypervisor died, the load balancers scheduled to that node would cease operation. With this update, these load balancers will be automatically rescheduled to a different agent. This feature is disabled by default and managed using `allow_automatic_lbaas_agent_failover`.

Description Nir Magnezi 2016-04-11 11:25:43 UTC 
Description of problem:
=======================
Currently, when a LBaaS agent goes offline the loadbalancers remain under that agent.
In a similar logic to 'allow_automatic_l3agent_failover', the neutron server should reschedule loadbalancers from dead lbaas agents.

this should be enabled with an option as well, such as: allow_automatic_lbaas_agent_failover
