Add support for adding cache to init scripts

install.sh
 * Copy Cache/etc/ to proper directory
 * Make a symbolic link from $CacheHome/etc/init.d/cache to
   /etc/init.d/cacheprod
 * Add init script to system configuration
 * Restart Cache using the new init script
etc/init.d/cache
 * change inst variable to prod as that is what install.sh expects
 * hardcode touch /var/lock/subsys/ commands to use name of script -
   currently done in a hackish way, but works
