Rename createCephNFS to upCephNFS and have it take a parameter with the
old active count. Rename deleteGanesha to downCephNFS and have it take a
parameter with the new desired active count. Both the existing callers
pass in "0" for the new count parameters.
Fix up the onUpdate handler for CephNFS objects, such that changes to
the active count are reflected in the number of active servers. Have it
pass in the appropriate values when scaling servers up or down.
Finally, fix downCephNFS to shut down the highest-index servers first
and count down, instead of doing them in the order they were started.
This should eventually allow us more predictable behavior when scaling
down the number of server nodes.
