Subject: [PATCH] Support use of GCE instance credentials (#109)

* Integration of MSI authentication with azurearm cloud driver (#105)

* allow empty service_account_private_key in GCE driver

Passing an emoty service_account_private_key to libcloud will enable
authentication using instance credentials, which is used by CaaSP in GCE.
