Include events when describing configmap

**What this PR does / why we need it**:
Currently `kubectl describe configmap/xxx` does not list events, even if there are events related to this congfigmap (and --show-events=true is explicitly passed). This PR makes it include events, same as for other resource types.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
