Move all event integration code to Dirt

[brant-livefront]

📔 Objective

This PR moves all of the event integrations code to Dirt. There should not be any code changes, other than the necessary cleanup of some of the import statements. A few files are erroneously showing as deleted instead of renamed, but I did legitimately delete one file - the interface for our old in-memory cache which is no longer used.

I've also moved the README to a more optimal location. It was way down under services. But now that we have an event integrations folder at the top with the service collection extension in it, it seemed like a much more direct place to put it.

dotnet format. Also please note that we need to fix any links to that readme once this lands.

@withinfocus format in the latest commit. 👍

I've got the link on my list of things to do - I noticed that when doing the latest contributing docs updates and we'd have had to change the link anyway since it's moving locations. 👍 I think that's the only link out there.
