Arvados

Working on ce8i5, I found a consistency issue when setting the Driver parameter for Volumes and Containers:CloudVMs:

• Volumes:Driver: expects "Azure" capitalized, or keepstore fails to start, with error
  

  {"error":"volume ce8i5-nyw5e-000000000000000: invalid driver \"azure\"","level":"error","msg":"exiting","time":"2020-08-26T21:56:48.248831360Z"}
  

• Containers:CloudVMs:Driver: expect "azure" lowercased or arvados-dispatch-cloud fails to start, with error:
  

  arvados-dispatch-cloud[108967]: {"PID":108967,"level":"fatal","msg":"error initializing driver: unsupported cloud driver \"Azure\"",
