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-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.

LDEV-4696 Make all @ManyToOne and @OneToOne lazy

Hibernate 3 used lazy loading of single-object relationships by default.

JPA's default setting is eager. When loading entities all references are

loaded immediately using JOINs. A large entity, like Learning Design,

can have a query consisting of 25 JOINs. It makes it very slow.

There is no way to change JPA's default behaviour. In order to make JPA

annotations behave like old Hibernate, each of them got an explicit

attribute saying that loading is lazy.
