extras: Add new options to group "virt"

Browse Source 
In some of the recent performance tests on gluster-as-vm-image-store
use-case, it has been observed that sometimes the lone fuse thread can
hit near-100% CPU utilization and become a performance bottleneck.
Enabling client-io-threads (in addition to bumping up epoll threads on
server and client side) has shown to be helpful in getting around this
bottleneck and pushing more IOPs.
