    Implement to provide host state management

properties:
    - name: RequestedHostTransition
      type: enum[self.Transition]
      default: "Off"
      description: >
          The desired host transition.  This will be preserved across AC
          power cycles of the BMC.

    - name: CurrentHostState
      type: enum[self.HostState]
      description: >
          A read-only property describing the current state of the host
          firmware. A user can determine if a system is in transition by
          comparing the CurrentHostState and the RequestedHostTransition
          properties.

    - name: RestartCause
      type: enum[self.RestartCause]
      default: "Unknown"
      description: >
          A property to define restart cause of a host.

          - name: "Reboot"
            description: >
                Host firmware should be rebooted. Chassis power will be cycled from
                off to on during this reboot

            description: >
                Host firmware be will notified to shutdown and once complete, the
                host firmware will be rebooted. Chassis power will remain on
                throughout the reboot

            description: >
                Host firmware will be rebooted without notification and chassis
                power will remain on throughout the reboot

    - name: HostState
      description: >
          The current state of the host firmware
      values:
          - name: "Off"
            description: >
                Host firmware is not running
          - name: "TransitioningToOff"
            description: >
                Host firmware is transitioning to an Off state
          - name: "Standby"
            description: >
                Host firmware is in a standby state. It is awaiting a Transition
                request to On to move to Running. This is an intermediate state
                that some implementations of this object may move to between Off
                and Running.
          - name: "Running"
            description: >
                Host firmware is running
          - name: "TransitioningToRunning"
            description: >
                Host firmware is transitioning to a Running state
          - name: "Quiesced"
            description: >
                Host firmware is quiesced. The host firmware is enabled but either
                unresponsive or only processing a restricted set of commands. This
                state can be a result of the host entering an error state or booting
                into a BIOS setup environment. The BootProgress property will
                provide details on which it is.
          - name: "DiagnosticMode"
            description: >
                Host firmware is capturing debug information. Powering off your
                system while the host is in this state will prevent the debug data
                from being properly collected. The host will move to one of the
                other states once complete.
