This change: 1. Adds credmanager service which handles credentials for AWS drivers. 2. Adds support for managing multiple AWS accounts through use of credmanager. Each account is mapped to a single project in keystone. 3. Adds support for multiple AZs by running one nova-compute and cinder-volume process per AZ. 4. Improves support for AWS networking in neutron. 5. Also, made few stability fixes in GCP and Azure drivers. Change-Id: I0f87005a924423397db659ab754caaa6cde90274
