NFS: report how long an NFS file system has been mounted
Add a field in nfs_server to record a timestamp when a mount succeeds.
Report the number of seconds the file system has been mounted via
nfs_show_stats().
Test plan:
Mount an NFS file system, watch the mountstats reports and compare with
clock time.
