Allow logger creation from an existing standard logger

[dbhoot]

Previously

You could not create a req.Logger from a log.Logger. Instead, you have to create one from an io.Writer.

Unfortunately, there are situations when you do not have access to the underlying io.Writer for your .Logger. This limits your ability to set the client logger using the tooling of your choice.

Now

You can usually convert your .Logger into a log.Logger. With this PR, you're now able to create a req.Logger from a log.Logger and set your client logger as needed.

@imroc what are your thoughts on this change? Please review when you have a moment.

I think it's better to rename to NewLoggerFromStandardLogger, a bit longer, but no ambiguity.

I agree. I was thinking of making that change anyway. Good call.

NewFromStandardLogger --> NewLoggerFromStandardLogger

Thanks
