sched-host-tran: implement host transition process

Set the scheduled time and host transition to trigger power on/off.

Tested:
1. Check the state first
 $ curl -k -H "X-Auth-Token: $token" https://$bmc/xyz/openbmc_project/state/host0
 {
   "data": {
     "AttemptsLeft": 3,
     "BootProgress": "xyz.openbmc_project.State.Boot.Progress.ProgressStages.Unspecified",
     "CurrentHostState": "xyz.openbmc_project.State.Host.HostState.Off",
     "OperatingSystemState": "xyz.openbmc_project.State.OperatingSystem.Status.OSStatus.Inactive",
     "RequestedHostTransition": "xyz.openbmc_project.State.Host.Transition.Off",
     "RequestedTransition": "xyz.openbmc_project.State.Host.Transition.On",
     "ScheduledTime": 0
   },
   "message": "200 OK",
   "status": "ok"
 }
2. Set a time in future
 # busctl set-property xyz.openbmc_project.State.ScheduledHostTransition \
   /xyz/openbmc_project/state/host0 \
   xyz.openbmc_project.State.ScheduledHostTransition ScheduledTime t 1582184830
 # busctl get-property xyz.openbmc_project.State.ScheduledHostTransition \
   /xyz/openbmc_project/state/host0 \
   xyz.openbmc_project.State.ScheduledHostTransition ScheduledTime
   t 1582184830
3. Check the state again after scheduled time
 Jan 15 06:38:20 WS-Seq-FW-2 phosphor-host-state-manager[442]: Host State transaction request
 $ curl -k -H "X-Auth-Token: $token" https://$bmc/xyz/openbmc_project/state/host0
 {
   "data": {
     "AttemptsLeft": 3,
     "BootProgress": "xyz.openbmc_project.State.Boot.Progress.ProgressStages.Unspecified",
     "CurrentHostState": "xyz.openbmc_project.State.Host.HostState.Running",
     "OperatingSystemState": "xyz.openbmc_project.State.OperatingSystem.Status.OSStatus.Inactive",
     "RequestedHostTransition": "xyz.openbmc_project.State.Host.Transition.On",
     "RequestedTransition": "xyz.openbmc_project.State.Host.Transition.On",
     "ScheduledTime": 0
   },
   "message": "200 OK",
   "status": "ok"
 }
4. Set quested transition to off
 # busctl set-property xyz.openbmc_project.State.ScheduledHostTransition \
   /xyz/openbmc_project/state/host0 \
   xyz.openbmc_project.State.ScheduledHostTransition RequestedTransition \
   s "xyz.openbmc_project.State.Host.Transition.Off"
 # busctl set-property xyz.openbmc_project.State.ScheduledHostTransition \
   /xyz/openbmc_project/state/host0 \
   xyz.openbmc_project.State.ScheduledHostTransition ScheduledTime t 1582250580
 $ curl -k -H "X-Auth-Token: $token" https://$bmc/xyz/openbmc_project/state/host0
 {
   "data": {
   "AttemptsLeft": 3,
   "BootProgress": "xyz.openbmc_project.State.Boot.Progress.ProgressStages.Unspecified",
   "CurrentHostState": "xyz.openbmc_project.State.Host.HostState.Off",
   "OperatingSystemState": "xyz.openbmc_project.State.OperatingSystem.Status.OSStatus.Inactive",
   "RequestedHostTransition": "xyz.openbmc_project.State.Host.Transition.Off"
   "RequestedTransition": "xyz.openbmc_project.State.Host.Transition.Off",
   "ScheduledTime": 0
   },
 "message": "200 OK",
 "status": "ok"
 }
