LDEV-5309 Fix removing units from numerical question

delete-orphan setting in QbQuestion units causes problems when importing

QbQuestion from XML. JPA does not recognise the collection parent and

fails on save. Another approach to removing units had to be found.

LDEV-5248, LDEV-4411 Mark some queries as cacheable

Query cache makes sense if tables which the query reference does not

change often. Each modification to table content invalidates the given

query's cache. Also each set of query parameters is a different cache

entry, so if there are various parameter values the cache overhead can

generate more load than benefit.

LDEV-5248, LDEV-4411 Add 2nd level cache to selected elements

Displaying Assessment results is too DB-intense for multiple learners.

We can enable a short-lived query cache for some entities which have

most impact on the results page. This way multiple requests can reuse

same objects from cache and there is little danger of inconsistency.
