Categorize events to distinguish between create/delete events

[harishspqr]

User Story
Currently the machine events does not indicate if they were related to create/delete of a Machine.
We need more metadata about the event to distinguish between create and delete events.

@noamran do you have an approach in mind for this?

@noamran do you have an approach in mind for this?

@ncdc not yet. Is there a specific approach you think I should be taking?

[ncdc]

We currently use .Eventf to record events. There is also .AnnotatedEventf, which would allow us to set annotations on the events when we create them. I think that's one possible approach (define a key and values indicating create vs delete)

[ncdc]

After talking to @yastij yesterday, it sounds like a newer events API is going to remove the annotation support. The recommended path forward is to use conditions instead of events. xref #1658

[ncdc]

Going through open unassigned issues in the v0.3.0 milestone. We have a decent amount of work left to do on features (control plane, clusterctl, etc). I think we need to defer it to v0.4.
