PackageManager Staging calls fail with ACCESS DENIED if made from inside a container.

[TimMangan]

The PackageManager functions to StageInPlace will all fail with an AccessDenied exception, if made by a process that is itself running in a container. The same code run unpackaged will succeed, but hey - we all want us writing modern code, right??? It took 3 weeks to figure out that this was the cause.

To be clear, this is code in a package that is trying to add a different package using AppAttach style attachment of a CIMfs package (not a package trying to update itself).

At a minimum the documentation on the following items should reflect this restriction (but it sure would be nice if the code just handled it).

StagePackageAsync(all flavors)
StagePackageByUriAsync()
