Delete the old event recorder

[kylehuntsman]

Deletes the pkg/eventrecorder directory.

I'm not sure if we're using pkg/eventrecorder/filelogserver/, but I moved it into pkg/aggregateeventrecorder/ just in case one of us is. If it's testing something, then it should be moved to a test. If it's a utility, then maybe it should be internal? Maybe it's own package if it's useful for a Lassie user to have? The original context of it is lost on me.

delete it, without old events it’s useless, it was only useful in the beginning
