Switch Atomic Runner to use a Service instead of a Scheduled Task

[clr2of8]

This code switches the atomic runner continuous testing to use a service instead of a scheduled task. The service will be called atomicrunnerservice and it will be installed in the c:\Windows\System32 directory by default. You can specify an alternate directory location for the service install with the -serviceInstallDir parameter.

If instead you would like to continue using the scheduled task instead of the service, specify the -asScheduledTask flag when calling Invoke-SetupAtomicRunner.

The code also includes a change that allows the -anyOS flag to be used with Invoke-AtomicRunner when-showDetails or -showDetailsBrief are used
