Old nuget.exe version

[trailmax]

In my VSTS build I've encountered a build error:

Executing: "D:/a/1/s/tools/nuget.exe" install "xunit.runner.console" -OutputDirectory "D:/a/1/s/tools" -Source "https://packages.nuget.org/api/v2" -ExcludeVersion -NonInteractive -NoCache
##[error]The 'xunit.runner.console 2.2.0' package requires NuGet client version '2.12' or above, but the current NuGet version is '2.8.60717.93'.

So nuget.exe is version. And it is provided by the plugin, not VSTS server - see the path - it is taking ../tools/nuget.exe. And looking on the plugin source, this line is probably the cause. It downloads nuget.exe from https://nuget.org/nuget.exe and examining that file it is of version 2.8.6.

I'm unsure if this is what nuget.org/nuget.exe had all the time, but this URL seems to be inconsistent with default build.ps1, where nuget.exe is downloaded from https://dist.nuget.org/win-x86-commandline/latest/nuget.exe

I'd quickly jump to do a PR to update the url, but there is already an issue for #4 that talks about a broader picture. So what should we do?

Oh.. I see there is work in progress for this already: #30
