Support saving multi ES cluster information?

[Jacky2]

Can you save multiple es cluster information, including account and password? After logging into cerebro, you only need to select different clusters to monitor different es information

[koy1619]

/opt/cerebro/conf/application.conf can config

eg

hosts = [
  {
    host = "http://10.10.3.2:9200"
    name = "nam2"
  },

  {
    host = "http://10.10.3.3:9200"
    name = "name1"
  },

  {
    host = "http://10.10.3.49200"
    name = "name3"
    auth = {
      username = "elastic"
      password = "ypCDmSVIN2C4"
    }
  }
]
