f3s/r-nodes: track NFS auto-repair script and systemd units in conf repo

Pull check-nfs-mount.sh, nfs-mount-monitor.service, and
nfs-mount-monitor.timer from r0/r1/r2 (confirmed identical on all
three nodes) into f3s/r-nodes/nfs-mount-monitor/.  Add
f3s/r-nodes/Rexfile with an idempotent nfs_mount_monitor task that
pushes the files to all three r-nodes as root and reloads systemd when
content changes.  Wire the new Rexfile into the repo root Rexfile.
