Hosting bundle does not propagate repair commands to inner bundles

[joeloff]

The hosting bundle nests the .NET runtime bundles. It defines separate install commands, but does not define a repair command. When the hosting bundle is executed from the commandline with /quiet /repair, it will repair ASP.NET Core and ANCM (because they are toplevel MSIs), but it won't repair the .NET runtime bundles.

The ExePackage in

aspnetcore/src/Installers/Windows/WindowsHostingBundle/DotNetCore.wxs

Line 12 in 963242a

InstallCommand="/quiet /norestart"

needs to be modified to also include

RepairCommand="/quiet /repair"
