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-5111 Display groups instead of students in chart when needed

If Assessment activity uses a leader, then only he gets his answers auto

saved. He counts as one student. But when he finishes the activity, his

answers get copied to other group members. Suddenly instead of 1 student

we get, say, 5 with same answers. This makes the answered questions

chart go crazy.

Now when leader selection is in use, group count is displayed instead of

student count in the chart.
