Emergencies should be less than the one provisioned.

[NiccoloSalvini]

Emergencies availbale are listed in hget_associated_cvp_from_emergency (code). However there are too many.

We agreed to take only a selection of 3 of them:

1. Emergenza COVID
2. Incendi boschivi del 2017
3. Terremoto Centro Italia 2016-2017

[NiccoloSalvini]

Moreover emergencies should be dependent on the country who is applying indicators. Say Italy has earthquakes, Spain should not want to do their indicators on the sam emergency, i.e. date. A possibility is to replicate what we did for Italy for each country. For the moment this behaviour can be accounted by enabling the user to select outbreak emergency date.
