From 3fc8b3f97df96198500bced0821d9c93f2a5d6d2 Mon Sep 17 00:00:00 2001 From: Harsha Dhake Date: Thu, 21 Feb 2019 02:30:24 -0500 Subject: [PATCH] Added credentials manager and updated omni drivers. 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.
