engine: Update Power Saving policy with power management

Add the logic that controls the automatic power management to
PowerSavingBalancePolicyUnit.

The unit got two new parameters:
- HostsInReserve - the amount of hosts with no VMs that should
                   be kept running
- EnableAutomaticHostPowerManagement - the feature enable flag

When there are too many hosts with no VMs, the algorithm will
select a host and put it first to maintenance and then down.

If we need more hosts, it will start them up.
