features/bitrot: tuanble object signing waiting time value for bitrot
Currently bitrot using 120 second waiting time for object to be signed after all fop's released. This signing waiting time value should be tunable. Command for changing the signing waiting time will be #gluster volume bitrot <VOLNAME> signing-time <waiting time value in second> Change-Id: I89f3121564c1bbd0825f60aae6147413a2fbd798 BUG: 1228680 Signed-off-by: Gaurav Kumar Garg <ggarg@redhat.com> Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/11105
