Description of problem: Currently memory accounting can be enabled by only '-DDEBUG' flag while compiling, which means we can't make use of rpm installed binary for some of the trouble shooting. We should bring in an option through glusterd/CLI so that memory accounting can be enabled on an volume on the fly. It need not be a persistent behavior (ie, no need to modify 'store'), but can be a global option while starting the volume. It is ok to say to get it into action, volume needs to be restarted. Version-Release number of selected component (if applicable): master
CHANGE: http://review.gluster.com/2856 (core: bring a cmdline option to set memory-accounting) merged in master by Vijay Bellur (vijay)
