Implement Generic Restart Resource(s)

[tgauth]

Summary of the new feature / enhancement

So if a process, service, or computer requires a reboot after Set, the resource running Set will output a property as true. Later, a "restart" resource will reference that output and run Test to evaluate if any upstream Sets needed a restart. If true, Set would handle the restart and could have properties to provide additional controls. Related to #50.

Proposed technical implementation details (optional)
