ci: Enable toolstate tracking on Azure

[alexcrichton]

Currently just run it through its paces but don't actually push to
official locations. Instead let's just push to a separate fork (mine) as
well as open issues in a separate fork (mine). Make sure that people
aren't pinged for these issues as well!

This should hopefully ensure that everything is working on Azure and
give us a chance to work through any issues that come up.

Fixes #61790
Fixes #61371

So I think I've got everything hooked up right, but I've surely forgotten something. Hopefully it won't cause too many issues!

I'd personally prefer to configure the issues URL and the delinking with environment variables instead of ifs in the code: this way we can do the Travis -> Azure switch without having to land PRs on the repo. Feel free to bikeshed the variable names.

[pietroalbini]

Oh, variables are also missing on the master pipeline:

variables:
- group: prod-credentials

[alexcrichton]

I continue to not really understand how those variable groups work. I clicked "link" in the web UI but I don't think that was done for the auto branch, and I don't know what effect this yml configuration has over that...

In any case everything else should be addressed!

re-r? @pietroalbini

I'll open an issue after this lands.

[pietroalbini]

Looks good now, thanks!

The way I understand it is that to use a variable group in a pipeline you have to declare it in the YAML. If the variable group is marked as "available to all pipelines" in the UI then that's all, otherwise you also have to authorize it from the UI as a security measure.

Looks like https://github.com/alexcrichton/rust-toolstate is receiving commits, but comments are failing on the master branch (https://dev.azure.com/rust-lang/rust/_build/results?buildId=716), will look into those now.

[alexcrichton]

Oh actually I think that that's an expected error. It's trying to create a comment on a PR in my repository, but that PR doesn't exist because it only exists in this repository.
