passwords when using ``overcloud export`` or
``overcloud cell export``.

Next steps:
===========\n
* Create roles file for cell stack, e.g.:
openstack overcloud roles generate --roles-path \\
/usr/share/openstack-tripleo-heat-templates/roles \\
-o cell_roles_data.yaml Compute CellController
* Create new flavor used to tag the cell controller
* Tag cell controller nodes into the new flavor
* Create cell parameter file as explained in bellow doc link
* Deploy the cell and make sure to add the following information
to the deploy command:
- additional environment files used for overcloud stack
- --stack <cellname>
- cell role file created
- the exported cell input information file {output_file}
- other specific parameter files for the cell\n
