Adding VSTS file

It seems that there is a consistent hang on Linux for Razor soon after we see this suspicious test that doesn't appear on TeamCity:

@NTaylorMullen do you have time to look into this or know of another Razor person who does?

[ryanbrandenburg]

Talked to Taylor in person, I'm going to see about getting him an image of the build machine that failed.

[ryanbrandenburg]

We're stalled on this until we can get a docker image that we can use to diagnose. I've talked to some people on the VSTS team, hopefully they have info soon.

[ryanbrandenburg]

This is stalled. Our current thinking is that something is causing the VSTS agent to lose connection with the server (maybe killing a process?), but we can't diagnose that ourselves so we need the VSTS people to look into it.

[natemcmaster]

Is this better now that we have more agents?

[ryanbrandenburg]

Looks like no, I don't think it's a matter of number of build agents so much as a communication problem between agent and server. Possibly our scripts hang in VSTS for some weird environment reason, but we're looking into it.

[natemcmaster]

I've been chatting with the VSTS folks. It looks like there is something in the VSTS infrastructure which doesn't play nice with background processes, such as rzc. I'm going to disable tests on VSTS Linux builds for now since we have coverage that works on Jenkins and TeamCity.

[natemcmaster]

@rynowak are there known issues with the tests "Queue_ProcessesNotifications_AndGoesBackToSleep"? It consistently fails on Windows in VSTS

[natemcmaster]

Queue_ProcessesNotifications_AndRestarts failed on Jenkins, so I'm going to open this as a flaky bug issue.

@HaoK can you review?

[natemcmaster]

#2506

[rynowak]

Yeah I think it's F L A K Y

[natemcmaster]

I've opened #2506 to follow up on flaky tests and #2507 to follow up on re-enabling Linux.
