Don't archive our nuget zip.  It's enormous and vastly decreases the number of artifacts we can store.

This reverts commit 936104f0.

This hardens the determinism job:
- Properly terminates build processes on exit
- Creates a zip file of all information needed for investigation on
failure

Change our archive logic to only store the items that we actually use for investigations.

closes #8550

Not required currently

double quotes
you have 'windows-roslyn-internal''

[‎10/‎14/‎2015 2:01 PM] Tanner Gooding:

label('windows-roslyn-internal')  
so two separate entries
[‎10/‎14/‎2015 2:02 PM] Jonathon Marolf:

[‎10/‎14/‎2015 2:03 PM] Tanner Gooding:

This change produced XML that was malformed based on what the pull request build plugin was expecting.  This was causing an exception in the pull request builder, cancelling pull request processing.  I modified the plugin to avoid the exception, but it still appears the Roslyn requests are malformed.

I am backing this out for now until we can understand what is really going on.

this enables `configVersion` to be set to `3` which will enable regex
