    [4.11/Future] CLOUDSTACK-9782: Host HA and KVM HA provider

    Host-HA offers investigation, fencing and recovery mechanisms for host that for
    any reason are malfunctioning. It uses Activity and Health checks to determine
    current host state based on which it may degrade a host or try to recover it. On
    failing to recover it, it may try to fence the host.
    
    The core feature is implemented in a hypervisor agnostic way, with two separate
    implementations of the driver/provider for Simulator and KVM hypervisors. The
    framework also allows for implementation of other hypervisor specific provider
    implementation in future.
    
    The Host-HA provider implementation for KVM hypervisor uses the out-of-band
    management sub-system to issue IPMI calls to reset (recover) or poweroff (fence)
    a host.
    
    The Host-HA provider implementation for Simulator provides a means of testing 
    and validating the core framework implementation.
