Allow log4j 2 loggers to be bound to slf4j logger

[tongguop]

Log4j 2 is released and it has async loggers, which are much faster then synchronized loggers. It would bre really nice that DW removes the hard coded logback logger and allows log4j 2 loggers to be bound

Log4j 2 is released and it has async loggers, which are much faster then synchronized loggers.

For which use cases? Is logging or the performance of logback really a problem in your Dropwizard applications?

There are currently no plans to replace logback in Dropwizard or to make the logging framework swappable.

We have a requirement to log every request including headers and payload. A lot of time user payloads are tens of KB, some times hundreds of KB(some extreme cases could reach MB level), async loggers are really needed in our situation so we don't need to wait on disk I/O.
