Condition lastUpdateTime is not preserved

[ash2k]

Before Bundle condition transition:

{"type":"Ready","status":"False","lastUpdateTime":null, "lastTransitionTime":"2018-09-25T12:40:59Z"}

Transition happens, lastUpdateTime is filled:

{"type":"Ready","status":"True", "lastUpdateTime":"2018-09-25T12:41:01Z","lastTransitionTime":"2018-09-25T12:41:01Z"}

After next reconciliation it is lost:

{"type":"Ready","status":"True", "lastUpdateTime":null, "lastTransitionTime":"2018-09-25T12:41:01Z"}

This is true for both Bundle's conditions and for resource's conditions.

Looks like all kube api types except for Deployment got rid of last update time (or never had it) in their conditions. See kubernetes/kubernetes#55268 (comment) and kubernetes/kubernetes#55272 (comment).
So the fix here would be to remove it to simplify it all.
