Michael Johnson 955bb88406 Refactor the failover flows
This patch refactors the failover flows to improve the performance
and reliability of failovers in Octavia.

Specific improvements are:
* More tasks and flows will retry when other OpenStack services are
  failing.
* Failover can now succeed even when all of the amphora are missing
  for a given load balancer.
* It will check and repair the load balancer VIP should the VIP
  port(s) become corrupted in neutron.
* It will cleanup extra resources that may be associated with a
  load balancer in the event of a cloud service failure.

This patch also removes some dead code.
