The CLI options are optional because if not specified the values are
pulled from the config file, which you can provide via the --config-file
option, and so you don't have to write URLs with credentials into
scripts. The fact it fails with "The specified transport_url and/or
database_connection combination already exists for another cell with
uuid" is because you're trying to create a cell using the same config as
another cell that already exists, so I'm not sure that this is a bug.

Bug description:
In "nova-manage cell_v2 create_cell" CLI help, the parameter ie.
"transport-url" and "database_connection" are mentioned as optional parameters
but they are treated as positional parameters.
If the optional parameters ie. "transport-url" and "database_connection" are
not provided, the CLI throws an error "The specified transport_url and/or
database_connection combination already exists for another cell with uuid
313fe809-ce91-490a-b147-4a74dc0ad071".
