[PATCH 2/3] Minor edit to OpenNebula driver - allows use of API_PROVIDER environment variable.

[ma...@redhat.com]

From: marios <ma...@redhat.com>

Can use either API_PROVIDER (or -P option to deltacloudd) or OCCI_URL environment variables
to specify location of the OpenNebula server. If both are set, OCCI_URL will take precendence.
