journald handler doesn't output user identity to metadata

[Juan Antonio Osorio Robles]

Even though the user_identity is set in the log message, the 'project_name', 'project_id', 'user_name' and 'user_id' are not set in the journald metadata as advertised by the handler; only the request_id is set. This is a sample record output:

It would be great if that data would be set in the metadata, as well as the user and project domains.

I'm not really familiar with journald. Are there fields built into its structure for that sort of info? Or should we add it to another field, like the message?

There is extra info that one can set. And actually, oslo.log's handler already has code to set that information, it's just never filled into the record.

I'm not sure why the patch in #4 was abandoned, but if someone else wants to pick this up I think we'd be happy to have all of the journald metadata filled in.
