Subject: [PATCH 1/5] detect deployed git HEAD in azure

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.

Counter-intuitively this needs to be FALSE so IIS can let go of
websockets and node can take over.
