[FEATREQ] extra-flattening

[kfsone]

I'd like to be able to output the extras list in a more human-facing way.

Current:

logger.remove()
logger.add(sys.stderr, format="{time:HH:MM:ss} | {level} | {message} {extra}")

outputs, e.g

23:13:11 | INFO | Testing {}
23:13:11 | INFO | With extras {'somekey': 'somevalue', 'x': 5}

I would rather it output:

23:13:11 | INFO | Testing 
23:13:11 | INFO | With extras somekey=somevalue, x=5

(I have a very non-technical audience and the presence of braces, colons, etc, generally shapes the way they interact with log output - as I've often found, it makes the difference between some users deliberately keep the context information out of their copy; others will assume the line is perfectly self-contained if there's programmer-stuff on it, and not paste context. This becomes increasingly more likely as the users' technical level decreases)

Hi @kfsone.

Yes, in a future release I was planning to improve the support for structured logging. In particular, I agree the formatting of extra arguments should be changed.
