LDEV-4293 Skip session creation when displaying error page

If the error was HTTP session being stale or incorrectly invalidated, we

should not try to use the same session to display the error page. The

error page should not require a session at all.

Also if making a decision which session to invalidate in case of double

login, always invalidate the other session and not current one as

otherwise it can lead to a loop of self-invalidating sessions.

LDEV-5273 Remove single VSA allocation interface from Assessment

Since UI for VSA allocation moved to Central, it is more difficult to

make it embedded within a tools own monitoring interface. It is probably

not needed too - a well designed VSA allocation UI for all questions

should be sufficient.

LDEV-5260 Rewrite polling to producer-subscriber model

Till now we had "are-learners-answers-updated" polling on controller

level.

It was rewritten to following scenario:

- method which stores learner answers is aware whether answers have

changed, i.e. it knows if charts need to be updated

- it flushes latest data to DB and puts tool content ID to Sink

- Sink notifies all interested Fluxes (currently only charts updating

one, but in the future other ones like updating table with answer % too)

- FluxMap holds a map of tool content ID -> interested hot publisher

Flux

- the Flux checks if it is interested in the tool content ID from the

Sink

- if so, it fetches data from DB and emits it to all subscribers, i.e.

opened monitoring windows with charts displayed

- data is cached so it is immediately available on for the next

subscriber

- data is throttled so calls to DB are not made too often

- if all subscribers are gone, the hot publisher Flux is still active; a

timeout is added which removes it from FluxMap when there were not emits

for the given time

LDEV-5259 Use MVC initialisation via annotation

Manually triggering controller scanning by adding an annotation handler

bean does not register all useful support beans. If

<mvc:annotation-driven> is used in spring-servlet.xml, all support beans

are registered via WebMvcConfigurer.

<mvc:path-matching suffix-pattern="true" /> need to be added because we

use .do suffix for Spring actions and suffix was turned off for Spring

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

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

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

added automatically. Also incorrect answers option does not get deleted

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.
