Subject: [PATCH 678/678] extras/group : add database workload profile

Running DB workload patterns with all perf xlators enabled as default has
resulted into some inconsistency issues. Based on the internal testing done by
Elko Kuric (ekuric@redhat.com) there're certain set of perf xlators which need
to be turned off to get these types of workload supported by Gluster.

The proposal is to leverage group profile infrastructure to group together all
those tunables at one place so that users just need to apply the profile to the
volume to use it for the data base workload.
