AsyncAppender now flushes log events when the application shuts down

* async appender workers are no longer daemon threads so they can flush
  partially buffered events to their delegates before stopping
* SLF4J request log stops the appenders when it's closed
* configured command stops the appenders when the execution finishes
* configured commands that execute asynchronously (e.g. ServerCommand)
  must now call cleanup when they finish execution

Add AbstractServerFactory#shutdownGracePeriod

We seemed to lose this option in the refactoring of 0.7. Jetty has
changed the way that shutdown is handled to better support multiple
lifecycles, but this still makes sense.
