Slowlogs don't log based on configured severity

Seems to imply that, e.g.,

PUT /_cluster/settings
{
    "transient" : {
        "logger.index.indexing.slowlog" : "WARN" 
    }
}

will inhibit logging DEBUG-level index.indexing.slowlog events, which is not the case. Slowlog doesn't behave the same way application logs do.

This applies to 1.x and 2.x.

Setting the slowlog level does work in index settings, just not cluster settings. The guide needs correction.
