Title: clean old libs and binaries

When upgrading kafka, this cookbook doesn't remove old libs and binaries.
You end up with a lib directory with several versions of kafka, zookeeper and other jars.
I guess same would apply to the bin directory with scripts.
So what I do, is delete libs/ and bin/ before a install.
