[tobiaszheller]

• reworks input params to search endpoints to use struct instead of 8/10 params: 87a7b76.

@zmb3 @espadolini I would like to get your opinion first just on 87a7b76

Could you add OTEL traces in this PR or do you want this to be just a change in how the parameters are passed?

edit: we already create a span for the call to the GetEvents rpc, so maybe it wouldn't be that useful without actually adding traces to individual parts in each audit log driver

let's add traces in separate PR, this is already large.
