Distinguish according to Tags

But need to repeat it in if  
"hosts "，"user"，"password"

I have a lot of "if" that I have to write multiple times

```auto
output {
    if "server4-apache-access" in [tags] {
        elasticsearch {
            hosts => ["http://localhost:9200"]
            index => "server4-apache-access-%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
            user => "elastic"
            password => "elastic"
        }
    }
    if "server4-apache-error" in [tags] {
        elasticsearch {
            hosts => ["http://localhost:9200"]
            index => "server4-apache-error-%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
            user => "elastic"
            password => "elastic"
        }
    }
}

```

That's the solution I've found so far

But I don't think this is particularly good 😝 😝
