Add a new command to export Ceph information from one or more Heat stacks to be used as input of another stack. Creates a valid YAML file with the CephExternalMultiConfig parameter populated. Also have export's export_password use yaml.safe_load in place of the deprecated yaml.load. Closes-Bug: #1895034 Change-Id: Ibdf9115e92c6b476b99d6df785b0c7e9f23991de
