Fix Jenkins slave #202

Replacing Jenkins slave with new slave that uses our Docker container. This is setup. Waiting to fix the stdout issue to enable automatic builds as otherwise they'd all fail right now . The stdout issue is fixed, but is blocked on CoreCLR being updated, and so blocks this. Jenkins slave fixed. VSO create date - 9/22/2015 9:18:00 VSO closed date - 10/1/2015 14:03:00
