Comment 0 for bug 1575898

In TripleO we seem to be hitting an issue where get_addr is returning before the output of the referenced resource is ready; this can be seen in the submission at: https://review.openstack.org/#/c/305751

That submission is creating a new output in the endpoint_map.yaml, see [1] and then it's updating the glance-registry role so that it gets its mysql connection string from the new output [2].

The mysql connection string is collected from the endpoint_map output in and passed as parameter to the role in [3]

As a result, the glance connection string ends up being invalid and the puppet module will default to sqlite [4]
