Add purge-events

[TomDeBacker]

Feature Description

Add the purge-events development mode functionality

Current Behaviour

Not possible

Wanted Behaviour

Be able to clear the events, using the connector without recreating the contexts/replicagroups. I'm using the connector for other things during TestContainer setup. This might be also be useful for #2461.

I'm not sure if this would fit in this repo tbh, especially since this is a feature only usable in dev-mode.. but I can ask :-) Maybe you have a better idea.

Possible Workarounds

Use cli or http request.

Thanks for filing this idea with us, @TomDeBacker.
My first thought about this idea is that it may require adjustment to the axon-server-api, as that's what the connector uses.
However, exposing a purge operation on the API does not immediately sound enticing to me, to be honest.

Nonetheless, we'll discuss the thought internally.
Perhaps there's a workaround from within the connector we can use for this.

Once a decision's been made, we'll update this ticket accordingly.
