Description

While testing Lustre master branch on our production system we ran into the issue of the timeout being incorrect on the MGS. This was causing the MGS to drop OSS and MDS connections. Also discovered if we changed the obd_timeout parameter anywhere to another value that value was never propagated to the rest of the system.
