Hot reload events

[CrosRoad95]

Idea is simple, make possible to call specific action after hot reload reload the code.
Currently you can't hot reload things like: fluent validation, auto mapper and much more libraries that have fixed configuration - with some events, when programmer change mapping, validation ect then it can be detected and reloaded.

This sounds more like a runtime ask?

Take a look at https://docs.microsoft.com/en-us/dotnet/api/system.reflection.metadata.metadataupdatehandlerattribute. It allows you to specify callbacks to call after the hot reload update.
