Description

Right now the caching audit logs aren't that useful, e.g.

2013-12-18 14:14:54,423 INFO  FSNamesystem.audit (FSNamesystem.java:logAuditMessage(7362)) - allowed=true	ugi=andrew (auth:SIMPLE)	ip=/127.0.0.1	cmd=addCacheDirective	src=null	dst=null	perm=null

It'd be good to include some more information when possible, like the path, pool, id, etc.
