feat(runtime): Add series implementation for event recorder

[pando85]

Motivation

The current implementation of the event recorder just creates new events which is not enough for my event handling expectations.

Solution

I added a recorder implementation more similar to the one in client-go library. This implementation caches events in local and groups isomorphic events to increment series count on similar events.

hey, thanks for this! looks largely sensible to me, gave a quick go over with some quick questions and minor nits, lmk if my thinking makes sense.

Now all tests were passed but I forgot about DCO again...

You can review it when you have time and if more improvements are needed I will work on them. If not I have to squash all those commits and we can merge.

thanks for the cleanups and sorry for the delay, have had a busy week. a few more small comments.

I fixed the issues with the tests and squashed all commits.
