    logging: don't set logging format strings for keystone
    
    Don't override those format strings since the overridden
    values are identical to those used by oslo.log by default [1].
    
    logging_exception_prefix is still set since it changes the logging
    format to use TRACE label for exceptions instead of default ERROR.

  This is because in devstack, we override the default log format string
  with the one that misses the info. Note that to make it work, it is
  not enough to fall back to default string, since it uses user_identity
  context field that is missing in neutron context object. That is
  because neutron.context.Context does not rely on oslo_context.Context
  when transforming it to_dict().

  The proper fix would be:

  - make neutron context reuse oslo_context.Context.to_dict()
  - make devstack not overwrite the default log format string

  Also note that log colorizer from devstack also rewrites the default
  format string value. In that case, we just need to update the string
  to include pid information.

  Also note that the issue may be more far reaching, since devstack
  rewrites the string for other services too (nova, ironic, among
  others).
