Vdsm sanlock I/O timeout value is now configurable (see sanlock:io_timeout option) and is documented in io_timeouts.md. vm_kill_paused_time option default value for killing VMs with leases still matches io_timeout default value, but if io_timeout is changed then the vm_kill_paused_time must be adjusted accordingly. There is no need to keep vm_kill_paused_time option since its correct value directly depends on io_timeout value. The corresponding value should be computed and applied automatically.
