Add support for List of datatype

[agoncal]

It would be good to have support for lists of datatypes. For example, here I could map a proposal which has a list of tags :

entity Proposal {
    title String,
    tags List<String>
}

This could generate the following entity :

@Entity 
public class Proposal {
   private String title;

   @ElementCollection
   @CollectionTable(name="tag_proposals", joinColumns=@JoinColumn(name="proposal_id"))
   @Column(name="tag")
   List<String> tags;

And why not allowing also sets :

entity Proposal {
    title String,
    rakings Set<Integer>,
    tags List<String>
}

That'd be interesting indeed! Again, all the heavy work would have to happen in the generator.

I also had many people asking me about this feature so I think might be worth to add in next major version

@agoncal I'll try some things this week-end

better to discuss together with jhipster/generator-jhipster#6275.

Was this feature forgotten or declined? is there any plans to have it in the future?. I can see it as part of the features described in the first post here#6275 but not included/explained at the end. The ticket also was closed with the tag for version 4.8 but I cannot find anything like List<String|Integer> in the documentation. Thanks.

@delkant Searching a little bit should have made you look at this issue
