fuse: Set limit on invalidate queue size
If the glusterfs fuse client process is unable to process the invalidate requests quickly enough, the number of such requests quickly grows large enough to use a significant amount of memory. We are now introducing another option to set an upper limit on these to prevent runaway memory usage.
