A "ro" or "rw" (or "nospectator"?) option in /etc/fstab would override the
addition of "spectator" to the mount options implied by <spectator/>.

We'd add a variable to /etc/sysconfig/cman that would tell the init script
to run fence_tool join.  If this was set, it would override the skipping
of that step implied by <spectator/>.

An explicit votes= setting for a node would override the 0 votes implied
by <spectator/>.
