More visibility on rate limits when some actions get rate limited for a long time (>5 minutes or even >30 minutes)

[waijie666]

Summary

I perform ClientUser.edit too frequently (more than 2 times for username change per hour) and getting rate limited. However I was waiting for quite some time (more than 10 minutes) and command not finishing and I am not getting any warning/error messages until I go enable debug logs.

Reproduction Steps

Just run this more than 2 times per hour

await self.bot.user.edit(username=username, avatar=binarybytes)

Expected Results

I expect to see some logs at WARNING level at least in the logging if the rate limit for retry is more than 5 minutes and in this case, it's almost one hour, so I wouldn't need to enable debug logs to find out the rate limit for this. I will let the devs decide the threshold but it should be at least something.

Actual Results

I had to enable logging.DEBUG to find out what's the issue.
