    Log warning when using token_flush
    
    The `keystone-manage token_flush` command was useful when we
    supported token format that were actually written to disk. Now that
    keystone has moved towards formats that don't require physical
    storage in the name of scalability, we no longer need the
    token_flush utility.
    
    This commit logs a warning when using `keystone-manage token_flush`
    so that people are aware they don't need to use it anymore if they
    are using supported upstream non-persistent token providers.

Title:
  keystone-manage token_flush fails unexpectedly

Status in OpenStack Identity (keystone):
  Fix Released

Bug description:
  The UUID token provider and SQL token storage driver were removed when
  Rocky opened for development [0]. The keystone-manage token_flush
  command was not removed with the rest of the code. As a result, if you
  run keystone-manage token_flush, you'll get an unexpected error:

  > keystone-manage token_flush
  CRITICAL keystone [-] Unhandled error: AttributeError: 'module' object has no attribute 'persistence'
  ERROR keystone Traceback (most recent call last):
  ERROR keystone   File "/usr/local/bin/keystone-manage", line 10, in <module>
  ERROR keystone     sys.exit(main())
  ERROR keystone   File "/opt/stack/keystone/keystone/cmd/manage.py", line 45, in main
  ERROR keystone     cli.main(argv=sys.argv, config_files=config_files)
  ERROR keystone   File "/opt/stack/keystone/keystone/cmd/cli.py", line 1412, in main
  ERROR keystone     CONF.command.cmd_class.main()
  ERROR keystone   File "/opt/stack/keystone/keystone/cmd/cli.py", line 889, in main
  ERROR keystone     token_manager = token.persistence.PersistenceManager()
  ERROR keystone AttributeError: 'module' object has no attribute 'persistence'
  ERROR keystone 

  Even though we've advertised the removal of UUID and SQL token storage
  for a long time, and people shouldn't be relying on this anymore, we
  should either fix this or remove the token_flush command.
