04737f5dbd
This patch implements upgrading keystone with zero downtime as the default installation process. Handlers have been modified to ensure that the first keystone node is stopped, facilitates the database migrations, and that it is started and available before restarting any other keystone nodes. Migrations also now only occur when there is a change within the installed keystone venv. This process is documented at http://docs.openstack.org/developer/keystone/upgrading.html#upgrading-without-downtime A new test scenario has been added for testing basic upgradability between releases. Implements: blueprint upgrade-testing Change-Id: I0d3cfcb80b64d005d60f4c8445f991855f844796
