LDEV-5272 Allow deallocating answers from VSA options

Also fix a bug: when a teacher allocates an answer, the learner's

question result UID was used. If the learner changed his/her answer

before teacher allocated it or refreshed the page, the new answer got

allocated while the teacher thought the old one was getting allocated.

Now all allocation happens based on real answer value.

Also recalculate scores on allocation even if a learner has not finished

the activity yet.

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
