    nova-manage cell_v2 map_cell0 exit 0
    
    This command used to always return 1 because it was returning a data
    structure used by another CLI function.  Now it exits 0 if the cell0
    mapping was created succesfully or was already there.

Title:
  nova-manage cell_v2 map_cell0 always returns a non-0 exit code

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  See the discussion in this review:

  https://review.openstack.org/#/c/409890/1/nova/cmd/manage.py@1289

  The map_cell0 CLI is really treated like a function and it's used by
  the simple_cell_setup command. If map_cell0 is used as a standalone
  command it always returns a non-0 exit code because it's returning a
  CellMapping object (or failing with a duplicate entry error if the
  cell0 mapping already exists).

  We should split the main part of the map_cell0 function out into a
  private method and then treat map_cell0 as a normal CLI with integer
  exit codes (0 on success, >0 on failure) and print out whatever
  information is needed when mapping cell0, like the uuid for example.
