   Travis is failing intermittently due to large log size, I've amended changes 
to reduce mvn build log and made changes in simulator integration test to pass 
for intermittent/edge cases.
   
   Considering LGTMs and test results, I'll merge this as soon as Travis is 
green.

   Ignoring intermittent test failures and new test failures around `isos`, 
this PR has enough LGTMs and test results now, I'll merge this tomorrow and 
wait for any new comments and objections.

   @nvazquez @DaanHoogland @borisstoyanov can you review the last change and 
any overall comments for me. Right now the feature is solid, all tests passing  
on simulator and kvm (centos6/7) for me. I'll kick a final round of tests now.

   Thanks @borisstoyanov, please hold further testings on it until I resolve 
conflicts and failing tests.

   As soon as the 4.10->4.11 db upgrade paths are fixed, I'll rebase and fix 
issues with the feature branch.

   @koushik-das Host-HA is disabled by default, it needs explicit configuration 
and to be enabled in order to be used. It further provides kill-switches 
(explicit disable APIs) for hosts across partitions (zone/cluster/host). 
Further, it has strict eligibility checks with pluggable 
mechanism/implementation that ensure only eligible resources take part in the 
HA lifecycle.
   
   The framework is written in an agnostic way to re-think our HA approach, and 
in comparison with the status quo this work provides mechanisms for eligibility 
checks, to degrade and recover a HA resource and policies/mechanisms to conduct 
(configurable) rounds of investigation and decisions based on a threshold 
ratios (granular/configurable). The new agnostic HA framework also has resource 
life cycle management using bounded ephemeral queues for managing very large 
environments (10k+ hosts), improved background polling task management against 
a FSM, reporting/alerting, ownership management of resource (in case of 
multiple-mgmt servers). Pluggability of the framework was another reason, it 
cleanly allows for large scale users to implement their own algorithms/logic to 
carry out various operations such as 
investigate/activity-checks/degrade/recover/fence etc. Due to several reasons 
and requirements, oobm could not been simply put in existing KVM specific VM-HA.
   
   In order for this to work, VM-HA and Host-HA must work in tandem and the 
cleanest way was to control VM-HA in a safe and backward-compatible way to 
over-ride the status returned by the KVM investigator based on Host HA FSM 
states. This strictly works only when host-ha is enabled for a host, I'll tag 
you on the specific code where this happen for you to verify. Any 
regressions/issues (if it creeps in) will not affect all HVs since the injected 
override is specific to KVM only. See our FS, last section on VM-HA Host-HA 
coordination. Lastly, remember this should not cause any issues post-upgrade 
for general users as the feature itself is disabled by default.
