Usage Events are not viewable by SpaceDevelopers, etc

[sethboyles]

Issue

According to the Roles matrix SpaceDevelopers, Supporters, and Auditors should be able to view UsageEvents.

The v3/app_usage_events endpoint is also accessible to all users, but only returns events if the user has global permissions:

cloud_controller_ng/app/controllers/v3/app_usage_events_controller.rb

Lines 10 to 13 in 01782fb

	app_usage_events = AppUsageEvent.where(guid: [])
	app_usage_events = AppUsageEventListFetcher.fetch_all(message, AppUsageEvent.dataset) if permission_queryer.can_read_globally?

It's unclear to me if this is a mistake in documentation or an incomplete implementation. Anyone know the history here?
