fuse: make background queue length configurable
* also make 'congestion_threshold' an option * make 'congestion_threshold' as 75% of background queue length if not explicitely specified * in glusterfsd.c, moved all the fuse option dictionary setting code to separate function Change-Id: Ie1680eefaed9377720770a09222282321bd4132e Signed-off-by: Amar Tumballi <amarts@redhat.com> BUG: 845214 Reviewed-on: http://review.gluster.org/3830 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>
