Description

Sorted API requests to the alerts endpoint results in data which is not sorted at all. Consider this query:

http://localhost:8080/api/v1/clusters/c1/alerts?fields=Alert/latest_timestamp&sortBy=Alert/latest_timestamp

The data is returned out of order. This is because the JPA sort is being placed into a HashSet instead of a LinkedHashSet.
