Creating a data stream per log level in Elasticsearch

[ArminShoeibi]

Hi there,

Do we have a feature like Index Decider in https://github.com/elastic/ecs-dotnet/tree/main/src/Elastic.Serilog.Sinks to create indexes per log level and date in the Data stream?

Here you can see IndexDecider and its tests
