can we have a test that shows backwards compatibility by passing jaeger.Logger as log.Logger?

Other than Yuri's comment it LGTM |

@black-adder Left some comments here - I think that this will be faster and easier to use if you change a few small things.

Please first check if Info is enabled, since we don't always want to incur the overhead of string formatting:
if l.logger.Facility().Enabled(zap.InfoLevel) {
l.logger.Info(fmt.Sprintf(msg, args))
}In general, if you're going to do formatted logging, you're better off wrapping *zap.SugaredLogger, which already has an efficient version of this API. Accepting that type also makes it clear to users that you're planning to do printf-style logging. Every *zap.Logger can easily and cheaply be converted to a *zap.SugaredLogger.

The exported function should take a *zap.Logger, since that's what all of zap's public APIs return.

This is a breaking change, we should maybe consider keeping the original log as is and add the zap-log directory, or rererelease 2.0.0 again
