LDEV-5125 Improve support for VSA questions import from Word file

VSA questions should have 2 options if they are going to be TBL

compatible. When importing from Word document only correct answers

option is required. The other one, incorrect answers option, now gets

added automatically. Also incorrect answers option does not get deleted

after editing via QB interface.

LDEV-4411 Reintroduce eager fetching and caching of QB options and units

There are several places in LAMS code where we need to detach QB

question entity from session to do copying and comparison. While another

approach can be found, it requires a lot of effort to rewrite now.

Fetching options from a detached question causes lazy initialisation

exceptions. We had to make them eagerly fetched again.

Collection caching is introduced too to address numerous queries run

with every question fetch.

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-3656 Clean up invalidated session from internal tracking mapping

These session should have been removed from the mapping when

SessionListener is called. Sometimes the listener is not called due to

WildFly internal bugs. We are left with a long list of stale sessions.

We should periodically clean up the mapping. Making it happen on runtime

stats fetch is as place as any other, plus it happens periodically.

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-4411 Native SQL queries are not cacheable by default

There seems to be a bug in Hibernate

https://hibernate.atlassian.net/browse/HHH-9111

There is a way to make native queries cacheable, but since there are so

few of them in LAMS, it is not worth the effort.
