Add almost all files to Microsoft.PowerShell.Commands.Management
One of them is Computer.cs that was listed in known issues.
We start to use a nuget packages generated for assemlbies that
cannot be listed in framework assemlbies, but exist in a GAC
on all windows machine and not a PowerShell assemblies
The first one is Microsoft.WSMan.Management
The packages are now dependencies of the `dnxcore50` framework itself,
rather than globally. The `compilationOptions` were pruned, with
`CORECLR` moved to frameworks, `_CORECLR` removed for all but
`Management.Infrastructure`, and `LINUX` moved to a new `Linux`
configuration, used only in `build.sh`. This configuration is
purposefully absent from libraries that do not use `LINUX`, so that it
is not relied upon without strong consideration. The dependencies
were pruned to reduce duplication.
Removes dependency on Microsoft.Extensions.Platform.Abstractions.
Makes use of native executable from `dotnet-cli` impossible; must use
`powershell` from monad-native.
