Bring Azure deploy scripts up to date

Commit 9934a0ace4a2a35463bf9c933eab9ab2b71a139a has changes that affect the global salt configs. 

Everything else is Azure specific.

Fixes #1731 #1485 
FYI -- We've standardized on the double bracket test operator as it is less error prone.  Don't see any problems here so it is really a nit.
