Disable reconfigure_token during upgrade (#2388)

If reconfigure_token is enable, it restarts admiral and harbor
services whenever it detects psc-config.properties changed. During
upgrade the new appliance will register itself to PSC and regenerate
psc-config.properties so admiral and harbor are restarted even they
are disabled.
