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.
