detect deployed git HEAD in azure

[bewest]

When deployed on MS azure, the available git commit used to deploy the
software is available in the SCM_COMMIT_ID environment variable.
We encourage all hosting providers to provide some similar facility to
avoid spawning spurious processes.

Thanks to @shanselman for reminders and pointers to the fix.

/Env/ only shows the global environment. But this one is very specific to one deployment, and it only available to the deployment script (and its child processes).

Ah that makes sense then. I'm trying to get it at runtime of the site to display on a page. Is a reason this isn't enabled? Am I going to be better off putting it in the msbuild task to embed it somewhere?

Two approaches:

During deployment, read this env and write the commit id to some file under your app's code (e.g. App_Data) that your runtime can read
Directly go after %home%\site\deployments\active which has the commit id
I suspect 2. is easier, though technically. it makes assumptions about the Kudu file structures that theoretically could change (but probably won't).
