analytics takes a long time to bring up service after restarting

After we restart analytics, it takes more than 30 seconds to bring service online. We have to increase the sleep time to 60 seconds.

curl -v -u Administrator:password -X POST http://172.23.96.8:8095/analytics/cluster/restart
sleep 30
curl -v -u Administrator:password http://172.23.96.8:8095/analytics/config/service

sleep 30
+ curl -v -u Administrator:password http://172.23.96.8:8095/analytics/config/service
