    Fix using template cell urls with nova-manage
    
    When nova-manage went to validate the transport-url given in config or on the
    command line, it was not doing the translation before passing the url to the
    oslo.messaging parse routine to check it. This exposes the format functions
    from the CellMapping object, and makes our _validate_transport_url() format
    the url before passing it to parse.
    
    This also adds a test that makes sure the template makes it into the database
    (as a template) and that it gets loaded out in translated form with an
    object load.

Title:
  when using templated cells urls, validation fails with create_cell
  when using {scheme} and {port}

  Fix Released

  In Progress

Bug description:
  When using templated cells urls as in
  https://docs.openstack.org/nova/rocky/user/cells.html#template-urls-
  in-cell-mappings , there is an issue with nova-manage parsing the
  transport url when we use {scheme} or {port}. The validation in nova-
  manage fails with:

  * {scheme} - No scheme specified:

  ()[root@undercloud /]# su nova -s /bin/bash -c "/usr/bin/nova-manage cell_v2 create_cell --name=default --database_connection='{scheme}://{username}:{password}@{hostname}/nova?{query}' --transport-url='{scheme}://{username}:{password}@{hostname}:{port}/?{query}' --verbose"
  Invalid transport URL: No scheme specified

  * {port} - expects an int for the port:

  ()[root@undercloud /]# su nova -s /bin/bash -c "/usr/bin/nova-manage cell_v2 create_cell --name=default --database_connection='{scheme}://{username}:{password}@{hostname}/nova?{query}' --transport-url='rabbit://{username}:{password}@{hostname}:{port}/?{query}' --verbose"
  Invalid transport URL: invalid literal for int() with base 10: '{port}'
