Handle resources that require restarts

[SteveL-MSFT]

Summary of the new feature / enhancement

Some changes to the system may require a reboot before additional changes can be applied. dsc itself shouldn't perform a reboot, but we may need a standardized way for resources to return that a reboot is required like _rebootRequested: true and then dsc just reports that as a standard result. Then something else performs the reboot when ready and re-runs the config until it completes or hits another reboot.
