LDEV-3115 Fix group removal on LD save in authoring

It seems that Hibernate does not like having entities violating unique keys in one collection. Even for a while and even though afterward the collection contains only unique entities.

LDEV-4411 Make relation from Evaluation to ToolActivity unidirectional

Hibernate can not lazy load properties connected with OneToOne

relationship. It means that with every fetch of ToolActivity its

ActivityEvaluation was also fetched, whether is was needed or not. It

made up even 10% of all queries sent to DB during a lesson.

By having the relationship unidirectional and fetching

ActivityEvaluation via DAO we ensure that it is fetched only when it is

needed. The code is not as nice, though.

LDEV-4411 Stop using collection cache for now

Cache annotations were commented out so we can come back to them easily

in the future.

Collection cache is not detecting changes made to entities. When a new

entity is added, collection cache does not see the change.

Properly tweaking concurrency strategy does not seem possible at the

moment, so we just turn it off.

LDEV-4288 Prevent duplicate entries in Gradebook activity table

Unique key allows us to track situations in which duplicate entries get

created in the table.

There is no point in copying Gradebook entries on tool content copy - we

never copy live lessons, only template Learning Designs which should not

have any gradebook entries set.

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

Similar to query cache, the collection cache makes sense if the table

which collection elements map to do not change often. Each modification

to table content invalidates the given collection cache.

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.
