[Question/Feature] How to set Index Lifecycle Policy

[Baklap4]

ECS integration/library project(s) (e.g. Elastic.CommonSchema.Serilog):
Elastic.Serilog.Sinks -> 8.6.0
Elastic.CommonSchema.Serilog -> 8.6.0
Is your feature request related to a problem? Please describe.
Currently the datastream will use the standard logs index lifecycle policy. How to configure this to another policy within our code?

Describe the solution you'd like
Programaticly define the index lifecycle policy and attach them to the datastream.

Describe alternatives you've considered
Changing the ilm through kibana, but this is a hassle

The bootstrap method exposes ilmPolicy as an argument

ecs-dotnet/src/Elastic.Ingest.Elasticsearch.CommonSchema/EcsDataStreamChannel.cs

Line 39 in b8e730d

public override bool BootstrapElasticsearch(BootstrapMethod bootstrapMethod, string? ilmPolicy = null)

But this is not wired through in any of the logging provider integrations. Will open a PR to add this!

Thanks for bringing this to my attention
