cluster/*: get logic to calculate min() of the 'stime' xattr
* in both distribute and replicate (ignoring stripe for now), add logic to calculate the min() of stime values. * What is a 'stime' ? Why is this required: - stime means 'slave xtime', mainly used to keep track of slave node's sync status when distributed geo-replication is used. Logic of calculating 'min()' for this stime is very important as in case of crashes/reboots/shutdown, we will have to 'restart' with crawling from stime time value from the mount point, which gives the 'min()' of all the bricks, which means, we don't miss syncing any files in the above cases.
