gitlab: Add new iterator with state change events

Retrieving events is spread across various various Gitlab APIs. This
makes importing and sorting Gitlab events by time quite complicated.

This commit replaces the old iterators with a goroutine/channel-based
iterator, which merges the individual Gitlab API streams into a single
(sorted) event stream.
