I want to add two more options to mongod.exe that would be used with --install and --reinstall. They would be for configuring mongod to run as a windows service with reduced permissions. Each would take an argument. Both would be required.
There would be two exceptions in which you could only specify the username and no password. Thous would be setting the service to run as Local Service (default, higher than administrator level services run at) or "Network Service"
Also, in keeping with the Services MMC snapin behavior, if the user lacks the "login as a service" permission it will be granted it.
