Allow the eventRecordQPS setting to be set. (#6880)

Browse source 
* Allow the eventRecordQPS setting to be set.

The eventRecordQPS parameter controls rate limiting for event recording. When zero, unlimited events can cause denial-of-service situations. For my situation, I don't need more than a setting of "5". This change allows me to configure the setting before creating the cluster.

* Allow the eventRecordQPS setting to be set.

The default settings (see types.go) is five. So, this change does not affect the cluster provisioning. However, it does allow for the setting to be changed.
