Generating CephExternalMultiConfig is error prone

[John Fulton]

When deploying DCN with storage the process to generate CephExternalMultiConfig as documented [1] is error prone. The 'openstack overcloud export' command can export control-plane data so that other heat stacks may use it as input but not ceph data and that makes it incomplete.

    Add openstack overcloud export ceph

    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.

    Document 'openstack overcloud export ceph' for DCN

    This update removes more than it adds becuase the new
    'openstack overcloud export ceph' command provided by
    the depends-on patch automates the information gathering
    necessary to create a Heat environment file with the
    CephExternalMultiConfig paramter populated.

    This change also gives the deployer the option to
    distribute the default openstack cephx keyring or to
    create an additional external keyring.
