Redis - sentinel failover processes:1. When multiple sentinel discovered and confirmed that there is something wrong with the master
2. Then elects a sentinel as leadership
3. To elect a slave as master
4. Notice the rest of the slave, who is the new master
5. Notice the change of the client a master-slave
6. In the end, the sentinel will wait for the old master raised, then put the new master became a slave
